For trust and safety
Send submissions that read as AI-written to a person for review. Our detector is tested on English academic writing only.
Review, then act
A flag from our detector is a reason to look closer. It is not proof that anyone cheated. Route flagged items to a reviewer, and remove nothing on a flag alone.
Where it is weak
Paid humanizer tools can hide machine writing from our detector. On heavily rewritten machine text, our detector and the commercial detector we compared it with often disagree: same verdict on 31 of 51 documents.
What it reads
Our detector reads English academic and student writing. It is not built or tested for other languages or other kinds of writing.
Volume
Send items through the API. Nothing is billed yet; each key is held to a ceiling on requests and words an hour, listed in the API reference.
Start with a paper you know.
Paste something you know a person wrote, such as your own writing, and see what our detector marks in it. It is free to start, with 2,000 words a day, or 1,000 papers a month with a verified school email.
