SENTENCE-LEVEL BREAKDOWN

Your text comes back marked up: high-AI, mixed and human passages colour-coded in place. Click any sentence to inspect its own probability.

A SCORE YOU CAN ARGUE WITH

A percentage, a letter grade and the evidence behind both — not a bare verdict you are asked to take on faith.

STUDENTS AND TEACHERS, ONE TOOL

Check your own draft before you hand it in, or a submission before you grade it. Same scan, same breakdown, either direction.

QUESTIONS

It is probabilistic, like every AI detector. It estimates likelihood and shows the sentences behind that estimate. No detector is 100% accurate, ours included — treat the result as one data point, not proof.

Yes. Every detector can, particularly on formal, structured or technical prose. That is exactly why the sentence-level breakdown is there: so you can judge the call yourself.

Free accounts can analyze up to 1,500 words per request, 20,000 words a month. Pro raises that to 5,000 words per request and 150,000 a month, with no daily limit.

You can run any text through it, and the sentence-level markup is far more useful than a bare percentage. Treat it as evidence to look at, never as a verdict: a score is not proof, and acting on one alone is how people get wrongly accused.

Free forever on 100 detections a day. Pro is $7/month for 150,000 words a month and 5,000-word requests.
