Where it matters
Where AI-Looking Content Costs You
Generated-sounding writing is judged in more places than Google. The same signals, even rhythm, stock phrases and no first-hand detail, cost credibility wherever a reader or a system decides whether to trust the text. Use the result to add what only you know, never as proof against an author.
SEO and GEO
Scaled, low-value pages get demoted whoever wrote them. AI answer engines quote pages with first-hand detail and skip generic ones. Pair this with the AI Visibility Checker.
Research and academia
Journals and funders now ask authors to disclose AI use. Check a paper, thesis or grant application before submission so the method and results carry it, not the phrasing.
Professional credibility
Proposals, reports and bios are discounted the moment they read as generated. The check shows where your own experience, numbers and decisions are missing.
AI products and datasets
Generated text fed back into a model degrades it. Screen retrieval knowledge bases, fine-tuning sets and training corpora for synthetic sources before they go in.
Publishing and journalism
Editors see which submissions lean on filler. Check drafts from writers for reporting, quotes and sources before the piece goes out under your name.
Hiring and freelance work
Cover letters and delivered copy are read by people who have seen a thousand generated versions. Check what you send, and what you receive.
Education
A risk estimate, never grounds for an accusation. Students can check an essay for generic phrasing before handing it in; tutors can use the ratings to talk about sources and evidence.
Disclosure and compliance
Transparency rules for AI-generated text are arriving, including the EU AI Act and platform policies. Knowing which pages read as generated shows where disclosure or a rewrite is needed.
Method
How the AI Content Checker Scores a Page
The checker reads the page's own text, and with a URL up to 15 sibling pages from the same section. Every rating comes with the reason behind it and a fix.
What the AI Content Checker Measures
- AI likelihood
- A 0 to 100 estimate from sentence rhythm, lexical variety, stock phrases, transitions, intensifiers, lists of three, em dashes and “not X, but Y” pairs, weighed against first-hand and evidence sentences. Fitted on labelled samples and shown with its measured error.
- AI writing patterns
- How closely the writing matches the surface habits of generated text: even sentence lengths, templated transitions, few concrete details.
- Scaled production
- With a URL, sibling pages are compared for shared openings, shared outlines, near-duplicates, swapped-word doorway pages and many pages last modified on the same day.
- Originality and reader purpose
- Does the page say what was done, for whom, when and with what result? Does it cite anything? Does it answer a question a reader has, or exist mainly to rank?
What the Checker Does Not Measure in AI Content
- Authorship. No tool can prove from text alone who or what wrote it, and this one does not try. The score is a likelihood with a published error rate.
- Images, video, non-English text. Only English prose in the page's server HTML is read.
- Links, traffic and behaviour. Google's own link, engagement and infrastructure signals are outside this check.
- Pages it cannot read. Under 80 words, behind a bot challenge, or loaded only with JavaScript: reported as not scored, never guessed.
FAQs
AI Content Checker FAQ
What does the AI likelihood score mean?
It is a 0 to 100 estimate of how strongly the writing matches patterns common in AI-generated text, such as even sentence rhythm, stock transitions, triplets and few first-hand details. It is a statistical estimate from writing patterns, not proof of who or what wrote the text.
Can an AI content checker prove that text was written by AI?
No. No checker can prove authorship from text alone, and this one does not claim to. It measures writing patterns and reports a likelihood with its measured error rate, so a human-written page with very formulaic writing can score high and a carefully edited AI draft can score low.
Why does the checker also rate scale, originality and purpose?
Google's spam policies target scaled content abuse: many pages produced mainly to rank rather than to help readers, whether or not AI wrote them. So the checker rates four things: AI writing patterns, signs of scaled production across sibling pages, originality and first-hand value, and whether the page serves a reader purpose. The fixes follow from those four ratings.
Should I reword my text so it scores lower?
No. Rewording to dodge a detector does not reduce the risk that matters, which is thin, repeated or unhelpful content. The fixes the checker suggests add first-hand detail, evidence and sources, or merge duplicate pages, because those are what make a page worth keeping in the index.
What can the checker not read?
It needs at least 80 words of English text in the page's server HTML. Pages that load their copy with JavaScript, sit behind a bot challenge, or are not in English are reported as not scored rather than given a number. It does not check images, video, links or how people behave on the site.
