A screenshot of ChatGPT reading: "[header] Legacy & Interpretation [body] The "Black Hole Edition" is not just a meme — it's a celebration of grassroots car culture, where ideas are limitless and fun is more important than spec sheets. Whether powered by a rotary engine, a V8 swap, or an imagined fighter jet turbine, the Miata remains the canvas for car enthusiasts worldwide."
LLMs tend to have an identifiable writing style.
This is a list of writing and formatting conventions typical of AI chatbots such as ChatGPT, with real examples taken from Wikipedia articles, drafts, comments, and other content. It is a field guide to help detect undisclosed AI-generated content on Wikipedia: while some of the signs may be broadly applicable, some may not apply in a non-Wikipedia context.[a] Not all text featuring these indicators is AI-generated, as the large language models that power AI chatbots are trained on human writing, including Wikipedia. Many elements of AI writing can be found in editorials, blogs, or fan fiction.

Moreover, this list is descriptive, not prescriptive; it consists of observations, not rules. Advice about formatting or language to avoid can be found in the policies and guidelines and the Manual of Style, but does not belong on this page.

The patterns listed here are also only potential signs of a problem, not the problem itself. While many of these issues are immediately obvious and easy to fix—e.g., excessive boldface, broken markup, citation style quirks—they can point to less outwardly visible problems that carry much more serious policy risks. Please do not merely treat these signs as the problems to be fixed; that could just make detection harder. The actual problems are those deeper concerns, so make sure to address them, either yourself or by flagging them, per the relevant guide.

The speedy deletion policy criterion G15 (LLM-generated pages without human review) lists some signs of AI writing, but is limited to the most objective ones. The remaining signs covered here are not sufficient on their own for speedy deletion.

Caveats
AI detection tools

WP:AIDETECTION
Do not solely rely on artificial intelligence content detection tools (such as GPTZero). While they perform better than random chance, these tools have non-trivial error rates.[1][2] Detectors can be susceptible to factors such as text modifications (e.g. paraphrasing, markup, and spacing changes) and the use of models not seen during detector training.[3] A high percentage of detected AI writing from the results of a detection tool is not a valid criterion for speedy deletion under G15.

Your detection ability

WP:AIDETECTIVE
Test your AI detection skills at Wikipedia:AI or not quiz.
Do not rely too much on your own judgment. Humans are notoriously bad at distinguishing human and LLM-generated text. While research on humans' abilities to detect AI-generated text is still limited, a 2025 study has shown that human ability to distinguish LLM text from human is no better than random chance.[4] Another 2025 study on German theses has shown that humans managed a "recognition rate of 57 % for AI texts and 64 % for human-generated texts".[5]

A 2025 preprint has shown that heavy users of LLMs can correctly determine whether an article was generated by AI about 90% of the time, which means that if you are an expert user of LLMs and you tag 10 pages as being AI-generated, you've probably made one false positive. Study participants who didn't use LLMs much did only slightly better than random chance (in both directions).[1]

Note, also, that human speech and writing is being influenced by LLMs, and thus they are becoming more similar. This was already evident in 2024, as shown by a study that detected a significant LLM influence in spoken content (e.g. conversational podcasts).[6] Further studies seem to confirm this influence on language,[7] including semantics and word choices.[8]

It is also worth noting that writers may adjust their behavior to avoid accusations of AI, or may be defensive about using AI tropes.

LLMs (and artificial neural networks in general) use statistical algorithms to guess (infer) what should come next based on a large corpus of training material. It thus tends to regress to the mean; that is, the result tends toward the most statistically likely result that applies to the widest variety of cases. It can simultaneously be a strength and a "tell" for detecting AI-generated content.

For example, LLMs are usually trained on data from the internet in which famous people are generally described with positive, important-sounding language. Consequently, the LLM tends to omit specific, unusual, nuanced facts (which are statistically rare) and replace them with more generic, positive descriptions (which are statistically common). Thus the highly specific "inventor of the first train-coupling device" might become "a revolutionary titan of industry". It is like shouting louder and louder that a portrait shows a uniquely important person, while the portrait itself is fading from a sharp photograph into a blurry, generic sketch. The subject becomes simultaneously less specific and more exaggerated.[b]

This statistical regression to the mean, a smoothing over of specific facts into generic statements, that could equally apply to many topics, makes AI-generated content easier to detect.

LLM writing often puffs up the importance of the subject matter by adding statements about how arbitrary aspects of the topic represent or contribute to a broader topic.[9][10] There is a distinct and easily identifiable repertoire of ways that it writes these statements.[11]

The Statistical Institute of Catalonia was officially established in 1989, marking a pivotal moment in the evolution of regional statistics in Spain. [...]

The founding of Idescat represented a significant shift toward regional statistical independence, enabling Catalonia to develop a statistical system tailored to its unique socio-economic context.

LLMs may even include these statements for even the most mundane of subjects like etymology or population data. Sometimes, they add hedging preambles acknowledging that the subject is of relatively low importance, before talking about its importance anyway.

Examples

During the Spanish colonial period, the name Bakunutan was hispanized to Bacnotan, a modification reflected in official documents preserved in the National Archives in Manila. This etymology highlights the enduring legacy of the community's resistance and the transformative power of unity in shaping its identity.

When talking about biology (e.g., when asked to discuss an animal or plant species), LLMs tend to over-emphasize connections to the broader ecosystem or environment, even when those connections are tenuous or generic. LLMs also tend to belabor the species' conservation status and research and preservation efforts, even if the status is unknown and no serious efforts exist.

Examples

Currently, there is no specific conservation assessment for Lethrinops lethrinus by the International Union for Conservation of Nature (IUCN). However, the general health of the Lake Malawi ecosystem is crucial for the survival of this and other endemic species. Factors such as overfishing, pollution, and habitat destruction could potentially impact their populations.

Canned emphasis on notability, attribution, and media coverage

Words to watch: independent coverage, local/regional/national/[country name] media outlets, music/business/tech outlets, trade publications, profiled in, written by a leading expert, active social media presence
Similarly, LLMs act as if the best way to prove that a subject is notable is to hit readers over the head with claims of notability, often by listing sources that a subject has been covered in and specifying what kind of sources they are (e.g., trade publications, regional media, etc). They often inaccurately attribute their own superficial analyses to the source. This is more common in text from AI tools released in 2025 or later.

Human-written press releases have of course also cited news clippings for decades, but LLMs specifically asked to write a Wikipedia article often echo the exact wording of Wikipedia's guidelines, such as "independent coverage."

Examples

On Wikipedia specifically, LLMs often painstakingly emphasize their sources in the body text—even for trivial coverage, uncontroversial facts, or other situations where a human Wikipedia editor would be more likely to either provide an inline citation or no source at all.

Examples

The restaurant has also been mentioned in ABC News coverage relating to incidents in the surrounding precinct, underscoring its role as a well-known late-night venue in the city [of Adelaide].

In articles about people or entities that use social media, LLMs will often note that they "maintain an active social media presence" or something similar. This wording is particularly idiosyncratic to AI text and relatively uncommon on Wikipedia before ~2024.

Examples

AI chatbots tend to insert superficial analysis of information, often in relation to its significance, recognition, or impact.[12] This is often done by attaching a present participle ("-ing") phrase at the end of sentences, sometimes with vague attributions to third parties (see below).[12][9]

For the purpose of Wikipedia, such comments are usually synthesis or unattributed opinions. Newer chatbots with retrieval-augmented generation (for example, an AI chatbot that can search the web) may attach these statements to named sources—e.g., "Roger Ebert highlighted the lasting influence"—regardless of whether those sources say anything close.

Examples

As of the April 2008 census, the population of Douera stood at approximately 56,998 inhabitants, creating a lively community within its borders. Situated in the central-north region of the country, Douera enjoys close proximity to the capital city, Algiers, further enhancing its significance as a dynamic hub of activity and culture.

Situated just a few miles from the U.S.-Mexico border—a line that often represents separation and division—the temple stands as a counter-symbol, emphasizing unity, togetherness, and transcendent faith. In a region where many families and communities span both countries, the temple fosters a sense of connection and shared purpose. Through its inclusive design and symbolic features, the McAllen Texas Temple is seen as a bridge across divides, embodying the spirit of unity that underlies its sacred purpose. Its bilingual monument sign, with inscriptions in both English and Spanish, underscores its role in bringing together Latter-day Saints from the United States and Mexico.

The temple’s architectural and decorative elements are thoughtfully imbued with local symbolism, reflecting the rich culture and landscape of the Rio Grande Valley. Citrus blossom motifs, seen throughout the exterior and interior, celebrate the area’s agricultural roots and its vital citrus industry. The temple’s color palette of blue, green, and gold resonates with the region’s natural beauty, symbolizing Texas bluebonnets, the Gulf of Mexico, and the diverse Texan landscapes. These colors and patterns evoke enduring faith and resilience, qualities that resonate deeply within this close-knit, cross-border community.

In design and structure, the McAllen Texas Temple honors the Spanish colonial heritage that has historically shaped the area. By incorporating these architectural elements, the temple connects to both the Latin American influences and the historic roots of the border region, creating a space where the past and present come together.

LLMs have serious problems keeping a neutral tone. Even when prompted to use an encyclopedic style, their output will often tend toward advertisement-like writing, or like the prose of a travel guide. This may happen when generating new text or rewriting existing text: for instance, an edit summary claiming a rewrite "removed promotional tone" while actually introducing it. This may also happen when editors are not deliberately trying to advertise a subject.[13]

Note: Not all promotional or spammy writing is AI-generated. LLMs tend to over-use the same set of promotional phrases no matter what the topic. Also, older LLMs (e.g., GPT-4) tend to output more blatantly positive text[14] than newer LLMs, which are more subtly positive and tend to avoid obviously superlative statements like "the best."

Language and grammar
AI-generated text displays consistent patterns in syntax, word choice, and sentence construction that human writing does not display to nearly the same degree. Conversely, it often struggles to match some syntactic and linguistic patterns characteristic of human writing. Some LLMs deviate more from human writing than others; for example, GPT-4o, the language model used by ChatGPT from May 2024 to August 2025, produces output with more variation from human writing than other contemporaneous language models.[12] Since these are linguistic patterns, they occur consistently regardless of the subject matter, which often gives AI-generated text an identifiable "voice".

Many studies have demonstrated that LLMs overuse specific words. These words started appearing far more frequently in text produced after 2022, when LLM chatbots became widely accessible.[11][17] They often co-occur in LLM output: where there is one, there are likely others.[20] While most of these studies have analyzed scientific abstracts or fiction, "AI vocabulary" words are also ubiquitous in LLM-based encyclopedias, such as Grokipedia, and in AI-generated Wikipedia text. One or two of these words appearing in an edit may be coincidental, but an edit (post-2022) introducing lots of them, lots of times, is one of the strongest tells for AI use.

The words that LLMs overuse have changed over time. For instance, the word delve was famously overused by ChatGPT in 2023 and early 2024, but became less frequent later in 2024, then dropped off sharply in 2025.[21][15] Below is a breakdown of which words frequently recur together during which LLM "era". While these are not hard cutoffs, they should give you a rough idea of how "earlier" vs "later" LLM output reads.

2023 to mid-2024 (GPT-4): Additionally, boasts, bolstered, crucial, delve, emphasizing, enduring, garner, intricate/intricacies, interplay, key, landscape, meticulous/meticulously, pivotal, underscore, tapestry, testament, valuable, vibrant
Mid-2024 to mid-2025 (GPT-4o): align with, bolstered, crucial, emphasizing, enhance, enduring, fostering, highlighting, pivotal, showcasing, underscore, vibrant
Mid-2025 and on (GPT-5): emphasizing, enhance, highlighting, showcasing (plus words associated with "Undue emphasis on notability, attribution, and media coverage")
The distribution of "AI vocabulary" is also somewhat different depending on the chatbot or LLM used.[12] Grok output is particularly idiosyncratic: it overuses superficially "scientific" words like causal, empirical, correlate, and continues to overuse underscore as of 2026.

This section is to be taken as literally as possible: a word being overused by AI does not imply that its synonyms are also overused. Also, keep context in mind. For example, while the figurative use of "underscore" is ubiquitous in earlier AI text, the word can also refer to a literal underline mark or to incidental music.

Muhammad, known as Haddad (the smith or iron-worker), and Hjajji Muhammad, the tile-cutter from Tabriz. These names highlight the collaborative nature of mosque construction and emphasize the contributions of skilled artisans. [...] For example, the repeated invocation of the names of Muhammad and the Twelve Imams in Kufic script highlights the Shi'ite character of the mosque and links its construction to the broader context of the Ilkhanid state's official adoption of Shi'ism under Oljeitu. [...] This inscription, commissioned during the reign of the Aq Qoyunlu ruler Uzun Hasan, also underscores the enduring practice of pious patronage for mosque upkeep and renovation.

Somali cuisine is an intricate and diverse fusion of a multitude of culinary influences, drawing from the rich tapestry of Arab, Indian, and Italian flavours. This culinary tapestry is a direct result of Somalia's longstanding heritage of vibrant trade and bustling commerce.
[...]

Additionally, a distinctive feature of Somali culinary tradition is the incorporation of camel meat and milk. They are considered a delicacy and serve as cherished and fundamental elements in the rich tapestry of Somali cuisine. [...]

An enduring testament to the influence of Italian colonial rule in Somalia is the widespread adoption of pasta and lasagne in the local culinary landscape, espicially in the south, showcasing how these dishes have integrated into the traditional diet alongside rice. [...]

Additionally, Somali merchants played a pivotal role in the global coffee trade, being one of the first to export coffee beans.

Avoidance of basic copulatives ("is"/"are" phrases)
Words to watch: serves as/stands as/marks/functions as/operates as/represents [a], boasts/features/maintains/offers [a], refers to
LLM-generated text often replaces simple constructions that use copulas such as is or are with constructions such as serves as a or mark the. This pattern has been observed in GPT and Gemini models.[16] One study documented an over 10% decrease in the usage of the words is and are in academic writing in 2023, with no major changes in their frequency before that.[22] Similarly, LLMs prefer to use marketing-related verbs like features, offers, and the like to their neutral synonym has. (Note: Do not confuse this with has used in the past perfect form, as in has been featured.) Sometimes--especially in more recent AI output--these constructions are more elaborate, e.g., ventured into politics as a candidate versus was a candidate, or began his career as versus was.

A similar decline in "is"/"are" constructions has been observed on Wikipedia, especially when controlling for lead paragraphs (which usually follow a formulaic structure of "[article subject] is...]" and thus skew the data).[16] It is particularly visible in AI copyedits, which will often "improve" text in this way. The study above also demonstrated that when GPT-3.5 was prompted to "Revise the following sentence" in 10,000 abstracts, the words is and are appeared less often in the revised versions.[22]

In lead sentences, LLMs will sometimes avoid is by writing refers to as though the article were about the word or term instead of the subject directly.

Negative parallelisms
Shortcut
WP:AIPARALLEL
See also: Negative parallelism
When LLMs describe a subject, their output may seem as though it is clearing up a common misconception, or as though the audience may be reaching an incomplete or incorrect conclusion about that subject. This kind of contrast can come across as trying to retroactively challenge such thinking by pointing out another characteristic that the subject may possess alongside (or in the place of) one or more previously-mentioned characteristics. While it is common among human writers (especially in "common misconceptions" or "myths busted" listicles), it is stereotypically an "AI sign."

Not just X, but also Y
It is common for LLMs to use parallel constructions involving "not", "but", or "however" such as "Not only ... but ..." or "It is not just ..., it's ...".[23][1][21]

Examples

In your most recent exchange, you referred to another editor’s comment as "bizarre" and "totally incorrect," following up with an assertion that their viewpoint was "bogus." This choice of language is not only dismissive but also unnecessarily harsh and confrontational. It shuts down the possibility of constructive dialogue and disrespects the effort that others put into contributing to this platform.

This kind of dismissive and confrontational attitude is not new. [...] This remark doesn’t just undermine the editor’s argument; it questions their very right to participate based on how long they’ve been active, which is contrary to the inclusive nature that Wikipedia aims to foster. New contributors should be encouraged, not belittled, and it’s disheartening to see you take such a dismissive stance.

Your sarcastic remark about adding "Eric Dick is a secret Democrat. [citation needed]" to the article further exemplifies this problematic behavior. Rather than engaging in a meaningful discussion, you chose to mock another editor’s argument, which only serves to create a hostile environment. This approach doesn’t help resolve disputes or improve content; it only escalates tensions and discourages productive collaboration.

Moreover, in another instance, you accused an editor of "bludgeoning discussion with screeds of AI generated waffle" and dismissed their contributions as "acres of fanciful extrapolation on Wikipedia policies." These comments are not just dismissive—they’re outright disrespectful. Accusations like these don’t belong in a professional and collaborative setting. They undermine the very spirit of Wikipedia, which is built on the idea that people with different perspectives can come together to create something valuable.

It’s important to recognize that everyone who contributes to Wikipedia—whether they’re new or experienced, whether they agree with you or not—deserves to be treated with respect. Collaboration, not confrontation, should be the goal. By continuing to engage with others in such a dismissive and harsh manner, you not only discourage participation but also damage the collaborative spirit that is essential to Wikipedia’s success.

I appreciate the feedback so far, but I want to clarify something that’s being overlooked. The issue here isn’t just sourcing—it’s framing. There’s a visible, growing movement around Northern English identity, documented across academic literature, social media, and grassroots activism. The fact that it doesn’t always use the exact phrase “Northern English nationalism” doesn’t mean it doesn’t exist. Movements evolve before they’re neatly labelled.

TikTok campaigns, dialect revival, and regional symbolism (like St Oswald’s stripes) are part of a broader cultural shift. Dismissing these as “not notable” or “original research” while allowing pages on Cornish nationalism, Wessex regionalism, and Yorkshire separatism suggests an inconsistency in how regional identity is treated. That’s not just a sourcing issue—it’s a systemic bias.

Not X, but Y
Another common LLM pattern is parallelisms that explicitly state that a particular item doesn't possess the first characteristic at all. Such constructions are often expressed as "It's not ..., it's ..." or "no ..., no ..., just ...".[19]

Examples

The viewer is presented with a self-image that is not grounded in visual mastery, but in what Amelia Jones terms “the performative enactment of subjectivity”.
[...]

This dispersal is not dissolution. Rather, it constitutes what Deleuze might describe as “becoming”—an identity in flux, constituted through iterative difference. Through this lens, Kusama’s self-portrait is not a mirror but a portal: not a representation of self, but a mechanism for its constant reinvention.

You say these sources “cover multiple events”? False. They echo the same viral incident and do it through a limited lens. This isn’t WP:NBIO — it’s WP:1EVENT in disguise, trying to wear a press badge like armor.

Now let’s talk BLP1E: This person is only in the news because of one isolated controversy. Not a career, not a body of work, not sustained relevance — just an algorithmic moment. And if we’re really upholding Wikipedia’s values, we don’t preserve pages built on the backs of virality alone, especially when it risks long-term harm to a living subject without lasting notability.

“Might as well get back on topic.”

Then let’s stay on topic, and the topic is not who feels warm fuzzies from visibility, it’s whether this article meets the threshold for inclusion. It doesn’t.

And finally — if you don’t want “a wall of text,” maybe don’t build a wall of shallow logic and expect people not to knock it down. This ain’t bludgeoning — it’s surgical teardown of a weak argument hiding behind fake neutrality.

Rule of three

  Soviet artistic constraints
  Non-conformist artists
  Their creativity
Vierny, after a visit in Moscow in the early 1970’s, committed to supporting artists resisting the constraints of socialist realism and discovered Yankilevskly, among others such as Ilya Kabakov and Erik Bulatov. In the challenging climate of Soviet artistic constraints, Yankilevsky, alongside other non-conformist artists, faced obstacles in expressing their creativity freely. Dina Vierny, recognizing the immense talent and the struggle these artists endured, played a pivotal role in aiding their artistic aspirations. [...]

In this new chapter of his life, Yankilevsky found himself amidst a community of like-minded artists who, despite diverse styles, shared a common goal—to break free from the confines of state-imposed artistic norms, particularly socialist realism. [...]

The move to Paris facilitated an environment where Yankilevsky could further explore and exhibit his distinctive artistic vision without the constraints imposed by the Soviet regime. Dina Vierny's unwavering support and commitment to the Russian avant-garde artists played a crucial role in fostering a space where their creativity could flourish, contributing to the rich tapestry of artistic expression in the vibrant cultural landscape of Paris. Vierny's commitment culminated in the groundbreaking exhibition "Russian Avant-Garde - Moscow 1973" at her Saint-Germain-des-Prés gallery, showcasing the diverse yet united front of non-conformist artists challenging the artistic norms of their time.

I am initiating this Request for Comment (RfC) to seek input from experienced editors and administrators regarding persistent policy compliance issues in this article, which covers a high-profile proposed acquisition involving Warner Bros. Discovery.
Despite repeated editing and cleanup efforts, the article continues to exhibit systemic problems that significantly undermine its encyclopedic quality and neutrality.

Key Issues Requiring Community Review
Undue Weight and Apparent Bias The article places disproportionate emphasis on Netflix, exceeding its relevance to the subject and creating an imbalanced narrative. This raises ongoing concerns under WP:NPOV and WP:UNDUE.
News Aggregation and Excessive Detail Large portions of the article read as compiled news reporting, with dense, minimally summarized content that appears to be copied or lightly paraphrased from sources. This conflicts with WP:NOTNEWS and WP:SUMMARYSTYLE.
Lack of High-Level Overview The article fails to present a clear, concise overview of the proposed acquisition. Instead, readers are confronted with fragmented detail without sufficient contextual framing.
Misplacement of Content Speculative analysis, reporting detail, and tangential information are frequently placed in inappropriate sections, weakening article structure and reader comprehension.
Prior Cleanup Efforts
I have personally conducted substantial editing, including:

[...]

However, these efforts have not resolved the underlying issues, suggesting that individual edits alone are insufficient and that broader consensus and oversight are required.

Questions for Comment
I respectfully request community input on the following:

Does the article currently give undue weight to Netflix or other peripheral entities?
Is the article failing to meet WP:NOTNEWS and WP:SUMMARYSTYLE standards due to excessive, real-time reporting?
Does the article require structural reorganization to provide a proper overview and improve section relevance?
Would administrative measures (e.g., guided restructuring, closer monitoring, or temporary page protection) be appropriate given the article’s visibility and edit patterns?
Closing
Given the prominence of this topic and the likelihood of continued drive-by or promotional editing, this article requires careful scrutiny by experienced contributors. The goal of this RfC is to establish clear consensus on how the article should be structured, weighted, and maintained in line with Wikipedia’s core content policies.

Instead of proper wikitext, a bullet point in an unordered list may appear as a bullet character (•), hyphen (-), en dash (–), hash (#), emoji, or similar character. Ordered lists (i.e. numbered lists) may use explicit numbers (such as 1.) instead of standard wikitext. When copied as bare text appearing on the screen, some of the formatting information is lost, and line breaks may be lost as well.

Overuse of em dashes

WP:AIDASH
While human editors and writers often use em dashes (—), LLM output uses them more often than nonprofessional human-written text of the same genre, and uses them in places where humans are more likely to use commas, parentheses, colons, or (misused) hyphens (-) and en dashes (–). LLMs especially tend to use em dashes in a formulaic, pat way, often mimicking "punched up" sales-like writing by over-emphasizing clauses or parallelisms.[21][19] AI-generated em dashes are usually surrounded by spaces, contrary to common typographic guidelines (which most human users of em dashes will be familiar with).

This sign is most useful when taken in combination with other indicators, not by itself. It is much more common on discussion pages than in article text. Also, because LLMs' use of em-dashes has become somewhat notorious, some AI companies have attempted to make their newer chatbots suppress their use, most notably OpenAI's GPT-5.1.[26]

Curly quotation marks and apostrophes
For non-AI-specific guidance about this, see Wikipedia:Manual of Style § Quotation characters, and Wikipedia:Manual of Style § Apostrophes.
Shortcut
WP:AICURLY
ChatGPT and DeepSeek typically use curly quotation marks (“...” or ‘...’) instead of straight quotation marks ("..." or '...'). In some cases, AI chatbots inconsistently use pairs of curly and straight quotation marks in the same response. They also tend to use the curly apostrophe (’), the same character as the curly right single quotation mark, instead of the straight apostrophe ('), such as in contractions and possessive forms. They may also do this inconsistently.

Curly quotes alone do not prove LLM use. Directional quotation marks (curly or typographer) are often used in published works written and edited using the Chicago Manual of Style.[27] Microsoft Word has a "smart quotes" feature that converts straight quotes to curly quotes. So does the default system-wide configuration on macOS and iOS devices, except on some applications (or if turned off, as may be necessary for programming). Grammar correcting tools such as LanguageTool may also have such a feature. Curly quotation marks and apostrophes are common in professionally typeset works such as major newspapers. Citation tools like Citer may repeat those that appear in the title of a web page: for example,

McClelland, Mac (2017-09-27). "When ‘Not Guilty’ Is a Life Sentence". The New York Times. Retrieved 2025-08-03.

Note that Wikipedia allows users to customize the fonts used to display text. Some fonts display matched curly apostrophes as straight, in which case the distinction is invisible to the user. Additionally, Gemini and Claude models typically do not use curly quotes.

Skipping heading levels
AI chatbots tend to skip level 2 headings (==) and start sections from the third level (===). Because doing so is against Wikipedia's accessibility and style conventions, it is therefore very unlikely for a manually-formatted page to have this quirk.

Thematic breaks before headings
AI chatbots sometimes include a thematic break (----) before each heading in a text (this is common in Markdown output).

Examples

=== Distinction from French “''[[List of English words of French origin|chiffon]]''” ===
Some claims have suggested that ''Ichafu'' derives from the French word chiffon (“rag” or "light cloth”). However, early lexicographic records do not support this interpretation and later sources differ in their explanations.

Editors sometimes paste text from an AI chatbot that was meant as correspondence, prewriting or advice, rather than article content. This may appear in article text or within comments (<-- -->). Chatbots prompted to produce a Wikipedia article or comment may also explicitly state that the text is meant for Wikipedia, and may mention various policies and guidelines in the output—often explicitly specifying that they're Wikipedia's conventions. Often the advice given by an AI chatbot is incorrect, misleading, or in contravention with policies or guidelines.

Knowledge-cutoff disclaimers and speculation about gaps in sources

WP:AIDISCLAIMER
Words to watch: as of [date],[c] Up to my last training update, as of my last knowledge update, While specific details are limited/scarce..., not widely available/documented/disclosed, ...in the provided/available sources/search results..., based on available information ...
A knowledge-cutoff disclaimer is a statement used by an AI chatbot to indicate that the information provided may be incomplete, inaccurate, or outdated.

If an LLM has a fixed knowledge cutoff, such as older large language models like GPT-3.5 or GPT-4 (usually the model's last training update), it is unable to provide any information on events or developments past that time. Older LLMs would often remind the user about this by outputting a disclaimer that the information in its response is accurate only up to a certain date, and may explicitly mention the knowledge cutoff in doing so.

Newer chatbots with retrieval-augmented generation may also fail to find sources on a given topic, or to find information within the sources a user provides. In these cases, they may output a statement, similar to a knowledge-cutoff disclaimer, claiming that the information is not publicly available. They may also pair it with text about what that information "likely" may be and why it is significant. This information is entirely speculative (including the very claim that it's "not documented") and may be based on loosely related topics or completely fabricated. When that unknown information is about an individual's personal life, this disclaimer often claims that the person "maintains a low profile", "keeps personal details private", etc. This is also speculative.

LLM-generated infobox edits may contain comments stating that text or images should be added if sources are found. Note: Comments in infoboxes, especially older infoboxes, are common—some templates automatically include them—and not an indicator of AI use. Anything but "Add ____", or variations on that specific wording, is actually more likely to indicate human text. Even then, there are exceptions; for example, articles with Template:Infobox military person often contain the boilerplate "Add spouse if reliably sourced", which predates LLMs.

Markup
Use of Markdown
Shortcuts
WP:MARKDOWN
WP:AIMARKDOWN
A lot of AI chatbots are not proficient in wikitext, the markup language used to instruct Wikipedia's MediaWiki software how to format an article. As wikitext is a niche markup language, found mostly on Wikipedia, other Wikimedia wikis, and other MediaWiki-based platforms like Miraheze, LLMs wikitext-formatted content is not prominent in their training data. While the corpora of chatbots did ingest millions of Wikipedia articles, these articles would not have been processed as text files containing wikitext syntax.

In chatbot apps, the output display is formatted with Markdown, a markup language conceptually similar to wikitext but much more widely applied. Meanwhile, the chatbots' preprompts typically instruct them to use markdown in their answers, such as when providing lists and writing with headings. That is, their system-level instructions often direct them to format outputs using Markdown, and the chatbot apps render its syntax as formatted text on a user's screen. For example, the system prompt for Claude Sonnet 3.5 (November 2024) includes:[28]

Claude uses Markdown formatting. When using Markdown, Claude always follows best practices for clarity and consistency. It always uses a single space after hash symbols for headers (e.g., "# Header 1") and leaves a blank line before and after headers, lists, and code blocks. For emphasis, Claude uses asterisks or underscores consistently (e.g., italic or bold). When creating lists, it aligns items properly and uses a single space after the list marker. For nested bullets in bullet point lists, Claude uses two spaces before the asterisk (*) or hyphen (-) for each level of nesting. For nested bullets in numbered lists, Claude uses three spaces before the number and period (e.g., "1.") for each level of nesting.

As the above indicates, Markdown syntax is completely different from wikitext. Markdown uses asterisks (*) or underscores (_) instead of single-quotes (') for bold and italic formatting, hash symbols (#) instead of equals signs (=) for section headings, parentheses (()) instead of square brackets ([]) around URLs, and three symbols (---, ***, or ___) instead of four hyphens (----) for thematic breaks.

When told to "generate an article", chatbots often default to using Markdown for the generated output. This formatting is preserved in clipboard text by the copy functions on some chatbot platforms. If instructed to generate content for Wikipedia, the chatbot might "realize" the need to generate Wikipedia-compatible code, and might include a message like Would you like me to ... turn this into actual Wikipedia markup format (`wikitext`)?[d] in its output. If the chatbot is told to proceed, the resulting syntax is often rudimentary, syntactically incorrect, or both. The chatbot might put its attempted-wikitext content in a Markdown-style fenced code block (its syntax for WP:PRE) surrounded by Markdown-based syntax and content, which may also be preserved by platform-specific copy-to-clipboard functions, leading to a telling footprint of both markup languages' syntax. This might include the appearance of three backticks in the text, such as: ```wikitext.[e][f]

The presence of faulty wikitext syntax mixed with Markdown syntax is a strong indicator that content is LLM-generated, especially if in the form of a fenced Markdown code block. However, Markdown alone is not such a strong indicator. Software developers, researchers, technical writers, and experienced internet users frequently use Markdown in tools like Obsidian and GitHub, and on platforms like Reddit, Discord, and Slack. Some writing tools and apps, such as iOS Notes, Google Docs, and Windows Notepad, support Markdown editing or exporting. The increasing ubiquity of Markdown may also lead new editors to expect or assume Wikipedia to support Markdown by default.

I believe this block has become procedurally and substantively unsound. Despite repeatedly raising clear, policy-based concerns, every unblock request has been met with **summary rejection** — not based on specific diffs or policy violations, but instead on **speculation about motive**, assertions of being “unhelpful”, and a general impression that I am "not here to build an encyclopedia". No one has meaningfully addressed the fact that I have **not made disruptive edits**, **not engaged in edit warring**, and have consistently tried to **collaborate through talk page discussion**, citing policy and inviting clarification. Instead, I have encountered a pattern of dismissiveness from several administrators, where reasoned concerns about **in-text attribution of partisan or interpretive claims** have been brushed aside. Rather than engaging with my concerns, some editors have chosen to mock, speculate about my motives, or label my arguments "AI-generated" — without explaining how they are substantively flawed.

JAF-GT300 cars are generally Japanese makes or specially constructed “silhouette” vehicles, distinct from the FIA [[Group GT3]] cars, also eligible in GT300【29†L582-L589】. The Japan Automobile Federation (JAF) is the national motorsport authority in Japan and co-sponsors Super GT, setting technical rules for JAF-GT cars【32†L142-L149】. In practice, a GT300 field includes three types of cars: (1) **JAF-GT** cars (JAF-regulation, often modified Japanese road cars or special designs), (2) **FIA GT3** cars (homologated under FIA GT3 rules), and (3) **Mother Chassis** (MC) cars (built on a standard tubular chassis by Dome)【29†L598-L606】.

Non-existent or out-of-place categories
Shortcut
WP:AIREDCAT
LLMs may hallucinate non-existent categories, sometimes for generic concepts that seem like plausible category titles (or SEO keywords), and sometimes because their training set includes obsolete and renamed categories. These will appear as red links. You may also find category redirects, such as the longtime spammer favorite Category:Entrepreneurs. Sometimes, broken categories may be deleted by reviewers, so if you suspect a page may be LLM-generated, it may be worth checking earlier revisions.

Of course, none of this section should be treated as a hard-and-fast rule. New users are unlikely to know about Wikipedia's style guidelines for these sections, and returning editors may be used to old categories that have since been deleted.

Non-existent templates
LLMs often hallucinate non-existent templates (especially plausible-sounding types of infoboxes) and template parameters. These will also appear as red links, and non-existent template parameters in existing templates have no effect. LLMs may also use templates that were deleted after their knowledge cutoff date (such as the lang-?? series).

Broken external links
If a new article or draft has multiple citations with external links, and several of them are broken (e.g., non-existent websites or 404 errors), this is a strong sign of an AI-generated page, particularly if the dead links are not found in website archiving sites like the Internet Archive. Most links become broken over time, but these factors make it unlikely that the link was ever real.

Watch out for: Links that don't work for you, but do work for other people (e.g., journal articles accessed through a university library); links that were mangled by bots and scripts (e.g., to add incorrect identifiers or to remove seemingly unnecessary parts of the URL); links that are missing the start or end (a sign of a human copy/pasting the URL).

Invalid DOI and ISBNs
For non-AI-specific guidance about DOI and ISBNs, see Wikipedia:DOI and Wikipedia:ISBN.
A checksum can be used to verify ISBNs. An invalid checksum is a very likely sign that an ISBN is incorrect, and citation templates display a warning if so. Similarly, DOIs are more resistant to link rot than regular hyperlinks. Unresolvable DOIs and invalid ISBNs can be indicators of hallucinated references.

DOIs that lead to unrelated articles
A LLM may generate references to non-existent scholarly articles with DOIs that appear valid but are, in reality, assigned to unrelated articles. Example passage generated by ChatGPT:

Ohm’s Law applies to many materials and components that are "ohmic," meaning their resistance remains constant regardless of the applied voltage or current. However, it does not hold for non-linear devices like diodes or transistors [1][2].

1. M. E. Van Valkenburg, “The validity and limitations of Ohm’s law in non-linear circuits,” Proceedings of the IEEE, vol. 62, no. 6, pp. 769–770, Jun. 1974. doi:10.1109/PROC.1974.9547

2. C. L. Fortescue, “Ohm’s Law in alternating current circuits,” Proceedings of the IEEE, vol. 55, no. 11, pp. 1934–1936, Nov. 1967. doi:10.1109/PROC.1967.6033

Both Proceedings of the IEEE citations are completely made up. The DOIs lead to different citations and have other problems as well. For instance, C. L. Fortescue was dead for 30+ years at the purported time of writing, and Vol 55, Issue 11 does not list any articles that match anything remotely close to the information given in reference 2.

Note: From 2018 to 2023, a UX issue in VisualEditor led many editors to accidentally insert references to PubMed articles with low ID numbers (PMIDs), resulting in obviously irrelevant citations like an article about rat livers (PMID 9) being cited in List of Disney television films in 2020. These may resemble AI hallucinations (and should be fixed regardless), but they generally are not.

Book citations without page numbers or URLs
LLMs often generate book citations that do not include page numbers. This passage, for example, was generated by ChatGPT:

Ohm's Law is a fundamental principle in the field of electrical engineering and physics that states the current passing through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant. Mathematically, it is expressed as V=IR, where V is the voltage, I is the current, and R is the resistance. The law was formulated by German physicist Georg Simon Ohm in 1827, and it serves as a cornerstone in the analysis and design of electrical circuits [1].

1. Dorf, R. C., & Svoboda, J. A. (2010). Introduction to Electric Circuits (8th ed.). Hoboken, NJ: John Wiley & Sons. ISBN 9780470521571.

The book reference appears valid – a book on electric circuits would likely have information about Ohm's law – but without the page number, that citation is not useful for verifying the claims in the prose.

Some LLM-generated book citations include page numbers, and the book exists, but the cited pages do not verify the text. Signs to look out for: the book is on a somewhat general topic or frequently referenced in its field, and the citation does not include a URL (not mandatory for book citations, but editors creating legitimate book citations often include a link to an online version of the text). Example:

Analysts note that traditionalists often appeal to prudence, stability, and Edmund Burke’s notion of “prescription,” while reactionaries invoke moral urgency and cultural emergency, framing the present as a deviation from an idealized past. [1]

1. Goldwater, Barry (1960). The Conscience of a Conservative. Victor Publishing. p. 12.

This may look like a reasonable citation, but searching an online version of the book for "Burke" produces no results.

Incorrect or unconventional use of references
Shortcut
WP:AICITESTYLE
AI tools may have been prompted to include references, and make an attempt to do so as Wikipedia expects, but fail with some key implementation details or stand out when compared with conventions.

Examples

In the below example, note the incorrect attempt at re-using references. The tool used here was not capable of searching for non-confabulated sources (as it was done the day before Bing Deep Search launched) but nonetheless found one real reference. The syntax for re-using the references was incorrect.

In this case, the Smith, R. J. source – being the "third source" the tool presumably generated the link 'https://pubmed.ncbi.nlm.nih.gov/3' (which has a PMID reference of 3) – is also completely irrelevant to the body of the article. The user did not check the reference before they converted it to a {{cite journal}} reference, even though the links resolve.

The LLM in this case has diligently included the incorrect re-use syntax after every single full stop.

For over thirty years, computers have been utilized in the rehabilitation of individuals with brain injuries. Initially, researchers delved into the potential of developing a "prosthetic memory."<ref>Fowler R, Hart J, Sheehan M. A prosthetic memory: an application of the prosthetic environment concept.

Edit summaries

WP:AISUMMARY
WP:AISUMM
In general, AI-generated edit summaries are often written as formal, first-person paragraphs, without abbreviations, and conspicuously echo the exact text of Wikipedia's policies or any maintenance tags on the article—for example, itemizing their adherence to "WP:NPOV" or "encyclopedic tone." They often mention things that they "ensured" or "avoided" doing, or include verbose justifications of minor edits; this is especially obvious if AI is used to "fix" text following suspicion of AI-use. They may also include other signs on this list, such as AI vocabulary, emoji, (attempted) list formatting, or markdown formatting. This section contains specific explanations and examples of some of the most common signs which are strongly indicative of AI generated edit summaries.

AI edit summaries strongly suggest that the edits themselves are also AI-generated, as it is unlikely someone would use AI for a simple summary but not the much more time-consuming task of writing.

ChatGPT I revised the content to provide a neutral and informative description of the Indira Gandhi National Centre for the Arts (IGNCA). The focus was on presenting the institution's objectives, approach, and programs in a way that adheres to Wikipedia's guidelines. The tone was adjusted to be more encyclopedic and less promotional.

Canned assurance of adherence to Wikipedia policies and guidelines
Words to watch: ensured that... adheres to, improved, in compliance/complies with, revised, verifiability, neutrality, neutral tone, encyclopedic tone
In line with the similarly-named comment-specific sign, AI generated edit summaries will often reassure the reader to a nearly self-conscious extent that the edit was made in compliance with various Wikipedia PAGs like neutrality and sourcing requirements.

Human editors do occasionally express that they are editing text because it violates a particular manual of style entry or guideline, but this is normally done in a brief and specific manner with a link to the particular item. For example, "removed excessive links per MOS:OVERLINK", whereas the AI-generated equivalent is usually more verbose and yet less specific (because the human editor behind the bot does not know the relevant guidelines to be able to prompt anything more specific than "make this more neutral"), explaining that they reorganised a section to "ensure neutrality," "improve attribution," "comply with the manual of style" or the likes.

The more of these assurances there are stacked in a single edit summary, especially if they cover a wide variety of "improvements" that a human editor is less likely to cover in a single edit, the stronger the sign.

Revised the Capabilities section for clarity and compliance with the Manual of Style; removed unnecessary language parameters, consolidated overlapping fine-tuning sections, corrected promotional wording, and distinguished preprints from established findings.

Specific mentions of "preserved" or "retained" information
Words to watch: preserved/preserving, retained/retaining
It is unusual for a human edit summary to include mention of material which was not edited. It is, however, exactly what one might expect from an AI which has been prompted to edit the article to accomplish X and Y but to specifically preserve or avoid changing Z.

Note (as is also shown in the examples below) that this typically goes hand in hand with the vague, canned assurances of adherence to/improvement in line with the PAGs/the MOS also discussed in this section; in the format of "Revised [section] to [improve/ensure/etc] [neutrality/verifiability/etc] while preserving [whatever]" or the inverse.

Overemphasis on presence/reliability of citations
Words to watch: added sourced [information/content/infobox/section], added [coverage/citations/references], improved attribution
One of the common general signs of AI generated text is the tendency to allude to the existence of coverage but not actually summarise the content of that coverage. A similar form of this manifests in edit summaries, where an excessive focus is placed on the fact that the content added is "sourced", "closely attributed" to "reliable sources", that "citations" or "coverage" were added, and so on.

A human editor is far more likely to focus on the actual content of the prose they added (e.g., "Added info about the artist's debut"} rather than only vaguely mentioning the source that information is linked to.

Miscellaneous
Pronounced shift in writing style
A sudden shift in an editor's writing style, such as unexpectedly flawless grammar compared to their other communication (e.g., talk page comments versus text added), may indicate the use of AI. This is especially likely if that other writing predates November 2022. The reverse also applies: If a user has edits that predate LLM chatbots, and their writing style has remained consistent between those older edits and their current ones (e.g., frequent use of boldface, list formatting, etc.), that suggests the newer edits are less likely to be AI.

A mismatch of user location, national ties of the topic to a variety of English, and the variety of English used may indicate the use of AI tools. A human writer from India writing about an Indian university would probably not use American English; however, several LLMs use American English by default unless prompted otherwise.[31]

Note that non-native English speakers also tend to mix up English varieties, and many writers use more formal prose in certain venues as a form of code switching (although that doesn't rule out writers doing that code switching with AI). These signs should raise suspicion only if there is a dramatic, not easily explainable shift in an editor's writing style.

More subtly, if an editor has used AI for several years, the writing style of their edits will often change in parallel with contemporaneous AI tools: their 2023 edits will resemble 2023 LLM output, their 2025 edits will resemble 2025 LLM output, and so on.

"Submission statements" in AfC drafts
This one is specific to drafts submitted by Articles for Creation. At least one LLM tends to insert "submission statements" supposedly intended for reviewers that supposedly explain why the subject is notable and why the draft meets Wikipedia guidelines. Of course, all this actually does is let reviewers know that the draft is LLM-generated, and should be declined or speedily deleted without a second thought.

Reviewer note (for AfC): This draft is a neutral and well-sourced biography of Portuguese public manager Jorge Patrão. All references are from independent, reliable sources (Público, Diário de Notícias, Jornal de Negócios, RTP, O Interior, Agência Lusa) covering his public career and cultural activity. It meets WP:RS and WP:BLP standards and demonstrates clear notability per WP:NBIO through: – Presidency of Serra da Estrela Tourism Region (1998–2013); – Presidency of Parkurbis – Covilhã Science and Technology Park; – Founding role in Rede de Judiarias de Portugal (member of the Council of Europe’s European Routes of Jewish Heritage); – Authorship of the book "1677 – A Fábrica d’El-Rei"; – Founder/curator of the Beatriz de Luna Art Collection (Old Master focus).

Pre-placed maintenance templates
Shortcut
WP:AIDECLINE
Occasionally a new editor creates a draft that includes an AFC review template already set to "declined". The template is also devoid of content with no reviewer reasoning given. The LLM apparently offers to add an AFC submission template to the draft, and then provides something like {{AfC submission|d}}, in which the "d" parameter pre-declines the draft by substituting {{AfC submission/declined}}. The draft's contribution history reveals that this template was inserted at some point by the draft's creator. Invariably the creator then asks on Wikipedia:WikiProject Articles for creation/Help desk or one of the other help pages why the draft was declined with no feedback. The presence of a content-free "submission declined" header is a strong indicator that the draft was LLM-generated.

LLMs have been known to create pages that already have maintenance templates that shouldn't plausibly be there, including maintenance tags and incorrect protection templates.

Some AI-generated user pages follow a certain format and often contain inline-header vertical lists and section headings with titles like Welcome To My User Page!, About Me, My Interests, and Let's Connect!. They may also contain emoji and bold text—or attempts at bold text with Markdown, which is typically the strongest giveaway that the content may have been generated by an LLM.

Permissions gaming
Permissions gaming is a form of disruptive editing where someone makes many benign-seeming but unconstructive edits, often on disparate topics or in quick succession, until their edit count is high enough to raise their user access level, allowing them to pursue their real goal of adding spam, vandalism, or contentious content.

Because AI chatbots are good at generating a lot of benign-looking content very quickly, people who game permissions after 2023 often do so with throwaway AI rewrites or additions to dozens of unrelated articles. If no one goes back and cleans up their edits, the result is a large swath of undetected and unreviewed AI content.

Note: This sign should only be used in one direction. Someone rapidly adding a lot of AI-generated text is not necessarily permissions gaming and should not be accused of it barring other evidence. However, if someone is found or reasonably suspected to be permissions gaming, and has done so by rapidly adding or changing a lot of text, those edits may be AI.

Differences between LLMs
Each model and version of AI chatbots have a distinctive way of writing (idiolect),[32][10], and what is typical for GPT-5 is not necessarily characteristic of GPT-4 or Gemini.

For example, text from ChatGPT (circa GPT-4o-2024-08-06) and Grok (Grok-Beta, as of late 2024/early 2025) exhibit characteristics that Gemini (1-5 Pro) and Claude (3.5-Sonnet) do not:

focusing on broader context is more characteristic of ChatGPT and Grok than Gemini and Claude.[10]
Gemini and Claude responses tend to be more concise than responses from ChatGPT and Grok.[i][10]
Though it's impossible to know for sure and there are many confounding variables, ChatGPT is likely the most widely used chatbot for Wikipedia edits.[33]

Signs of human writing
Age of text relative to ChatGPT launch
ChatGPT was launched to the public on November 30, 2022. Although OpenAI had similarly powerful LLMs before then, they were paid services and not easily accessible or known to lay people. Thus, if an edit was made before November 30, 2022, AI use can be safely ruled out for the corresponding text. While some older writing displays some of the AI signs given in this list, and may even convincingly appear to have been AI-generated, the vastness of Wikipedia allows for these coincidences.

Ability to explain one's own editorial choices
Editors should be able to explain why they made an edit or mistake. For example, if an editor inserts a URL that appears fabricated, you can ask how the mix-up occurred instead of jumping to conclusions. If they can supply the correct link and explain it as a human error (perhaps a typo), or share the relevant passage from the real source, that points to an ordinary human error.

Syntax
LLMs writing or editing Wikipedia articles will attempt, by default, to produce text in what it considers to be "formal, neutral, encyclopedic tone." This manifests as AI-generated text avoiding certain syntactic constructions that are both common in human writing and often perfectly acceptable per the Manual of Style--and in some cases, even preferred by it.

Specifically, the following have been empirically observed, over 25 years of Wikipedia writing, to be more common in Wikipedia articles written by humans than in AI-generated text:

Simple is/has phrases,[22] such as there is a, it has a.
Words with complex, stiff or euphemistic synonyms, such as wrote (versus authored), moved (versus relocated), used (versus utilized), tried (versus attempted), died (versus passed away).
Superlative or definitive statements, such as one of the best, is the only, was the first
Hedging qualifiers and intensifiers,[34] such as very, perhaps, tends to.
Isolated wordy constructions such as as a result of, in order to, all of the, a part of, or the fact that.
Ineffective indicators
False accusations of AI use can drive away new editors and foster an atmosphere of suspicion. Before claiming AI was used, consider whether the Dunning–Kruger effect or confirmation bias may be clouding your judgement. Detecting LLM texts on the basis of style alone is not as easy as it seems, see WP:AIDETECTIVE in this page. Here are several somewhat commonly used indicators that are ineffective in LLM detection—and may even indicate the opposite.

Perfect grammar – While modern LLMs are known for high grammatical proficiency, many editors are also skilled writers or come from professional writing backgrounds. (See also § Sudden shift in English variety use.)
Combination of casual and formal registers, or language that sounds both "clinical" and "emotional" – This may indicate the casual writing of a person in a technical field, such as computer science. It may also indicate youth, a preference for mixed registers, playfulness, or neurodivergence. In the case of a wiki, it may simply be the result of multiple editors adding to a page.
"Bland" or "robotic" prose – LLM output has specific traits, as detailed above, and it skews positive and verbose by default. While these tendencies are formulaic, they may not scan as "robotic" to those unfamiliar with AI writing.[35]
"Fancy", "academic", or "formal" prose – While LLMs disproportionately favor certain words and phrases, many of which are longer and have more difficult readability scores than some of their synonyms, these are specific words. The correlation does not extend to all formal, academic, or "fancy"-sounding prose.[1]
Transition words (in isolation) – Older AI text tended to formulaically overuse certain transitions like Additionally, Consequently, and Notably, often to begin sentences. However, only a few transition words and phrases are known to be overused by AI in this way. This pattern also has precedence in essay-like writing by humans and is accepted by many style guides, so this is not a strong tell.
Unsourced content – More than 570,000 articles are tagged as needing citations, and most of them predate LLMs. Meanwhile, since modern LLM chatbots can search the web and view sources a user provides to it, citations are fairly common now in AI-generated text. This does not mean they are accurate citations, but they are there.
Bizarre wikitext – While LLMs may hallucinate templates or generate wikitext code with invalid syntax for reasons explained in § Use of Markdown, they are not likely to generate content with certain random-seeming, "inexplicable" errors and artifacts (excluding the ones listed here in § Markup). Bizarrely placed HTML tags like <span> are more indicative of poorly programmed browser extensions or a known bug with Wikipedia's content translation tool (T113137). Misplaced syntax like ''Catch-22 i''s a satirical novel. (rendered as "Catch-22 is a satirical novel.") are more indicative of mistakes in VisualEditor, where such errors are harder to notice than in source editing.
Correct wikitext – Especially if the person is using the visual editor or has found the Preview button, getting the formatting correct, even for complex templates, is normal.
Historical indicators
The following indicators were common in text generated by older AI models, but are much less frequent in newer models. They may still be useful for finding older undetected AI-generated edits. Dates are approximate.

Didactic disclaimers (November 2022–2024)
Shortcut
WP:DIDACTIC
For non-AI-specific guidance about this, see Wikipedia:Manual of Style/Words to watch § Editorializing.
Words to watch: it's important/critical/crucial to note/remember/consider, worth noting, may vary...
Older LLMs (~2023) often added disclaimers about topics being "important to note".[36] This frequently took the form of advice to an imagined reader regarding safety or controversial topics, or disambiguating topics that varied in different locales/jurisdictions. Several such disclaimers appear in OpenAI's GPT-4 system card as examples of "partial refusals".[37]

Examples

The emergence of these informal groups reflects a growing recognition of the interconnected nature of urban issues and the potential for ANCs to play a role in shaping citywide policies. However, it's important to note that these caucuses operate outside the formal ANC structure and their influence on policy decisions may vary.

WP:CONCLUSION
WP:INCONCLUSION
Words to watch: In summary, In conclusion, Overall ...
When generating longer outputs (such as when told to "write an article"), older LLMs often added sections titled "Conclusion" or similar, and often ended paragraphs or sections by summarizing and restating its core idea.[31]

Examples

In summary, the educational and training trajectory for nurse scientists typically involves a progression from a master's degree in nursing to a Doctor of Philosophy in Nursing, followed by postdoctoral training in nursing research. This structured pathway ensures that nurse scientists acquire the necessary knowledge and skills to engage in rigorous research and contribute meaningfully to the advancement of nursing science.

In summary, I believe the detailed coverage of Eric Dick’s involvement with HCDE is appropriate and valuable for readers. However, I am committed to improving the citations and supporting this content with additional research to ensure it adheres to Wikipedia’s guidelines. Please feel free to share any additional thoughts you might have.
Conclusion

In conclusion, while the concern about undue focus on Eric Dick's involvement with HCDE is valid, the solution should not be to simply cut large sections of content without proper research and verification. Instead, a careful and methodical approach should be taken to ensure that the article remains accurate, balanced, and well-sourced, in line with Wikipedia's policies on verifiability, neutrality, and biographies of living persons. Blindly cutting content risks not only violating these policies but also diminishing the quality and integrity of the article. Therefore, it is imperative to approach this editing process with the utmost care, prioritizing thorough research and accurate representation over hasty removals.

Conclusion: I’m committed to ensuring that all content in the article meets Wikipedia’s standards for reliability and neutrality. However, this requires a collaborative effort. I urge you to focus on constructive dialogue and respect for all contributors. Let’s work together to strengthen the article rather than engage in unnecessary conflict.

Conclusion:

Your current approach to editing and discussion, characterized by dismissive language, unfounded accusations, and a refusal to engage constructively, may potentially violate Wikipedia’s Civility policy and undermine the collaborative nature of the platform. I strongly urge you to reconsider how you interact with fellow editors. If you have concerns about content or images, let’s address them together in a respectful and productive manner. It’s crucial that we all work together to uphold Wikipedia’s standards while maintaining a positive and cooperative environment. Please try being nice to people for a change.

In conclusion, I am here to collaborate and work together to improve the article. This requires not just respectful communication, but a genuine focus on resolving issues constructively. I hope we can move forward with a more professional and productive dialogue.

In summary, I have consistently proposed well-sourced edits and have made clear my willingness to modify the content based on further discussion and research. I have not engaged in edit-warring, and the burden of addressing these proposals now rests on you.

Prompt refusal
Words to watch: as an AI language model, as a large language model, I cannot offer medical advice, but I can..., I'm sorry ...
In the past, AI chatbots occasionally declined to answer prompts as written, usually with apologies and reminders that they are AI language models. Attempting to be helpful, chatbots often gave suggestions or answers to alternative, similar requests. Outright refusals have become increasingly rare.

Examples

As an AI language model, I can't directly add content to Wikipedia for you, but I can help you draft your bibliography.

Abrupt cut offs
AI tools used to abruptly stop generating content if an excessive number of tokens had been used for a single response, and further responses required the user to select "continue generating", at least in the case of ChatGPT.

This method is not foolproof, as a malformed copy/paste from one's local computer can also cause this. It may also indicate a copyright violation rather than the use of an LLM.

Outdated access-date parameters
In some AI-assisted text, citations may include an access-date by default, but the date can look unexpectedly old relative to when the edit was made (for example, an article created in December 2025 containing multiple citations with |access-date=12 December 2024). However, newer chatbots seldom produce this error, and older access-date values can occur legitimately (copied citations, offline work, batch moves/merges).

Notes
 Specifically, this guide is less useful for texts which are not informational writing. For example, the many tells specific to fiction (whispering woods, Elara Voss, etc.) are less relevant in Wikipedia and are not listed here.
 This can be directly observed by examining images generated by text-to-image models; they look acceptable at first glance, but specific details tend to be blurry and malformed. This is especially true for background objects and text.
