AI essay checker
This page exists mainly to be clear about something: essay detection is the single worst-behaved application of AI detection, and the consequences of a false positive fall on a person. You can run the check here, and you will get a considered answer with its reasoning shown — but it is not evidence of misconduct and should never be presented as such.
If you are a student wanting to know whether your own writing might be flagged, this is a reasonable use. If you are an educator, treat a high score as a prompt to talk to the student about their process, not as a finding.

Frequently asked questions
Can a school rely on an AI detector?
No. Several universities have withdrawn detector-based processes after false positives, and major vendors carry explicit warnings against using scores as sole evidence. Use it to start a conversation, not to reach a conclusion.
My own essay was flagged. What does that mean?
Most often it means you write in a consistent, formal register with even sentence lengths — which the detector cannot distinguish from generated prose. It is not an accusation, and it does not mean your writing is bad.
Does editing AI text make it undetectable?
Substantially, yes. This is one reason detection cannot carry the weight people want it to: the failure mode is not random, it systematically favours whoever edited more.
