Free AI Content Detector
Paste a passage to see a category-by-category read on the phrasing patterns that AI models over-use, with the exact phrases highlighted in your text. Built for editing, not accusations.
Free checks run on a lighter AI model and are capped at 2,000 words and 2 checks per day. Sign in and use credits for the most thorough analysis with our strongest model.
This is a heuristic aid, not proof. AI detectors, including this one, produce false positives and false negatives. Never use it to accuse or penalize anyone. Use it only as an editing aid to spot phrasing that reads generic.
How the AI content detector works
It does not have a secret AI-detection oracle, and neither does any tool. Instead it reads your text for the specific phrasing patterns that AI models statistically over-use compared with human fiction, and reports them openly so you can judge for yourself.
Paste your passage
Drop in a paragraph, a chapter excerpt, a blurb, or anything you want a second read on, and choose fiction or nonfiction. The whole passage is analyzed, never a truncated sample.
See a category-by-category read
You get a separate result for each pattern category, from stock phrases and body-reaction clichés to theme telegraphing, each with a plain-language explanation of what it found and why.
See the flagged phrases and fix them
Each category highlights the exact phrases in your text, so you can revise the writing instead of arguing with a number, or hand a flagged line to our paraphrasing tool.
Who uses the AI content detector
It is built for editing and self-review, not for policing. The goal is stronger writing, not a gotcha.
Authors self-editing a draft
You used AI to draft and want to catch the passages that still read generic before you sell an AI-assisted book on Amazon. The highlights point you straight to the phrases worth rewriting in your own voice.
Editors giving feedback
Instead of a vague 'this feels AI', you get specific patterns to discuss with a writer, so the note is about craft rather than an accusation.
Bloggers and marketers polishing copy
Blurbs and posts often drift into cliché and stock phrasing. Spot those tells and swap in specifics before you publish.
Frequently asked questions
No, and no AI detector is. Detection is fundamentally unreliable: tools produce both false positives, flagging genuine human writing, and false negatives, missing edited AI text. This tool reports visible phrasing patterns, not proof of how the text was produced. Treat every result as one opinion to inform your editing, never as evidence.
It should never be used that way. Because these results are unreliable and easy to get wrong, using any AI detector to accuse or penalize someone is unfair and risks punishing innocent people. This tool is for self-editing and constructive feedback about the writing itself. Do not use it to make accusations or disciplinary decisions.
It checks category by category: stock phrases, voice-attribution tags, body-reaction clichés, negative parallelism, sentence-length variety, and narrative-craft signals like theme telegraphing, emotional telling, and generic detail. Each pattern is judged against how often human fiction uses it, and common everyday phrasing is never flagged. These patterns can appear in human writing too, which is exactly why the result is an editing aid rather than a verdict.
No. A flag means the text shows a phrasing pattern that AI models over-use, but a human leaning on clichés can produce the same pattern. Likewise a clean result does not prove a human wrote it, since AI text can be edited to read naturally. Use the flagged phrases to improve the writing, not to draw conclusions about the author.
Cut stock openers, replace abstract claims with concrete examples and real detail, vary your sentence lengths deliberately, and dramatize emotion through action instead of naming it. Each category shows the exact phrases it flagged, so you can revise with intent rather than guessing.
