A field of tools and techniques—classifiers, perplexity scoring, n-gram analysis—used to flag text likely generated by AI, with notable false-positive rates.
Sitefire's SlopShape spots AI-written company blog posts at 97.0% macro-F1 from page structure alone, and at 96.1% after each model rewords its own output. Paraphrasing generated copy hides little from it, though the test reworded text without reordering any page's sections.

Graphite counted 13,000 phrases that AI models use at least twice as often as human writers, with a different set for every model version. Editors cleaning AI drafts need a phrase list tied to the model that wrote them, rebuilt at each release.
Reality
Superhuman's purchase of AI detector GPTZero returned at least 10 times the $13.5 million it raised, a source told Fortune. Treated as a price, that puts a floor of $135 million under a deal with undisclosed terms.
Reality
Pangram Labs and UMass Amherst researchers put AI-generated text at about 31% of August 2026 web tokens and fit a scaling law for when it starts to hurt. For teams that pretrain on web crawls, AI text becomes a measured line item in the data budget, with a curve for its marginal value.
Reality
Dartmouth College is investigating AI use in provost Santiago Schnell's writing after a detector scored his essay on AI cheating 100% AI-written. In his apology he names disclosure as the rule he broke, and a college can apply that rule to its provost and its students alike.
Reality
France's Académie Goncourt dropped Thélyson Orélien's novel from its first selection, citing plagiarism and analyses that AI most likely wrote most of it. For anyone who sells AI checks, the case shows a likelihood score counting once a plagiarism record sat beside it.

LinkedIn asks users to flag suspected AI posts, Substack labels them and Anthropic watermarks Claude's text, while detector Pangram claims 99.7% accuracy. Readers can now check anything an executive signs. That makes a written rule on AI drafting necessary.
Reality
Anthropic says it is watermarking Claude text to satisfy the EU AI Act Transparency Code and plans a detection API. The exposure sits with teams shipping generated work as their own.

A detector run over 490,000 Common Crawl pages puts a number on synthetic text in the crawlable web, and the number is uneven enough to change how you build a training set.

Researchers counted at least 40,000 people in Nairobi writing other people's coursework early this decade. The trade is close to gone, and the work that still pays is rewriting model output by hand until the software cannot tell.

Pangram's own 4.0 testing put the false-positive rate on AI-assisted documents at 0.01 percent, 4 percent or 7 percent depending on how the test text was produced, and the website shows the smallest of the three.
Reality
404 Media found contractors who read real ChatGPT conversations have been fired for handing in model-generated work, and the internal documents show the sanctioned check on them is a human judging the overall pattern.
Reality
Three Northeastern researchers describe chatbot vocabulary and sentence habits moving into human prose. The measurement behind that description is a preprint on how people and ChatGPT copy each other mid-conversation.
Reality
Two detection studies put machine-written text across large slices of Amazon's self-published shelf, and the sales figures underneath one of them show a market that grew in dollars while thinning out per title.
Reality
Fast Company reports that Pangram beats rival detectors in independent testing, without naming an error rate, and Substack, NewsGuard and an exam platform are already running it on writing whose authors never opted in.
Reality
Super exists because Pangram V4 stopped working against StealthGPT's old rewriter, and the launch report puts the evasion number next to a factual-consistency score of 82 percent on the same 100 samples.
Reality
Chalmers researchers trained Swedish and English detectors on 2,800 pre-chatbot motions and then watched flagged texts climb from near zero to almost one in ten by 2025-2026, with no member declaring the help.
Reality
Pangram scored a Wall Street Journal guest column as entirely machine-written, the author cheerfully agreed, and the paper answered with a test about the author's standing rather than the text. Semafor puts the flagged share of op-eds at about 3%.
Reality
Pangram has 24 employees and a percentage that Substack now shows to readers, so publishers and prize juries are making irreversible calls on a number checked mainly in early independent tests, by a company that has since shipped a new model.
Reality
Cancer-journal editors are already catching undisclosed LLM use in peer review with commercial software. The unresolved question is what happens to a flagged researcher who says no.
