Free AI detector tool to check any text

Our AI detector is a neural network that has read an enormous amount of writing from both people and machines. Over all that text it learned the small habits that tell the two apart. It does not read for meaning the way you do. It reads for those habits.

AI writing has a feel to it once you have seen enough. Sentences come out a similar length. The next word is usually the safe, expected one. It hedges, repeats sentence shapes, and explains more than it needs to. People write with more bumps. A short sentence here, a long winding one there, an odd word, a joke that does not quite land.

On clean test data the model is right most of the time, comfortably above nine in ten. Real text is messier than test data, so read the score as a strong hint rather than a fact. Anyone who promises you certainty is selling something.

Two things drag accuracy down. Short text, because there is not enough to read. And edited text, because once a person reworks an AI draft or runs it through a rewriter, the tells start to fade. A clean low score means nothing jumped out, not that AI was never involved.

The check happens in memory on our own server. As soon as you have a score, your text is dropped. No logs, no database, no training set.

There is no account holding a history of your checks either.

Teachers check work they were not expecting from a particular student. Editors screen pitches before spending time on them. Students run their own essays and papers to see what reads as too smooth. Hiring teams glance at cover letters. The honest use in every case is the same. A prompt to look closer, never a final word.
