AI Detector for Teachers

Paste any text below to see how likely it was written by AI. Free, no signup, scored instantly in your browser. Built for teachers grading essays — sentence-level evidence shows exactly which lines triggered the score, so you never accuse on a number alone.

Runs locally in your browser — text never leaves this page.

FAQ

Can I check a whole class of essays at once?

Yes. Use the Batch files tab on the main AI Detector — drop up to 50 .txt files or a .zip and every file gets its own score. Files never leave your browser.

How should teachers use AI detection scores?

As one signal, never as proof. Detectors can misjudge formulaic human writing. Open the sentence breakdown, discuss it with the student, and weigh it against their in-class writing.
