Paste any text and get an honest likelihood band for whether AI wrote it — based on sentence rhythm, repetition and AI-typical phrasing. No black-box percentage, no sign-up: a straight read of the signals in the writing itself.
AI-written text has habits: very even sentence lengths, repeated stock phrases, and a smooth, predictable rhythm. Human writing is messier. This AI text checker measures those patterns — sentence-length variation, repetition and common AI phrasing — and reports a likelihood band rather than a fake-precise score. Treat the result as a signal to read more closely, not proof: no checker can decide authorship for certain, and this one is honest about that.
How to use the AI text checker
Paste the text — an essay, article, application or post you want to check.
Run the check — the tool analyses sentence rhythm, repetition and phrasing.
Read the band — see whether the text reads as likely human, mixed, or likely AI-written, and why.
Use it as a signal — combine the result with your own reading before drawing conclusions.

Shows its reasoning — sentence rhythm, repetition and phrasing, explained.
Works on any text — essays, cover letters, articles and posts.
Free, no sign-up — paste and check straight away.
Frequently asked questions
How does the AI text checker work?
It analyses the patterns AI writing tends to leave behind — how much sentence lengths vary, how much phrasing repeats, and whether AI-typical expressions appear — then reports a likelihood band instead of a single made-up percentage.
Can an AI checker prove a human did not write something?
No. Checkers estimate likelihood from writing patterns; they cannot prove authorship. Use this result as one signal alongside your own judgement, especially before making any serious decision about a piece of writing.
How much text should I paste?
A few paragraphs or more gives the checker enough rhythm and repetition to measure. Very short snippets produce weaker signals.
