Free AI Content Detector
Paste a passage to get an honest likelihood estimate of how AI-generated it reads, with the specific signals behind the score and tips to make it sound more human.
This is a heuristic estimate, not proof. AI detectors, including this one, produce false positives and false negatives. Never use a score like this to accuse or penalize anyone. Use it only as an editing aid to spot writing 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 writing patterns that commonly show up in AI drafts 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. The whole passage is analyzed, never a truncated sample.
Get a likelihood estimate
You get a 0 to 100 estimate and a hedged label such as 'reads mostly human' or 'likely AI-assisted', plus a plain-language summary of why it landed there.
See the signals and fix them
Each flagged passage shows the exact sentence, the pattern behind it, and a concrete rewrite tip, so you can revise the writing instead of arguing with a number.
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. The signals point you straight to the sentences 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 cliche and rule-of-three filler. Spot those tells and swap in specifics before you publish.
