Free Tool
AI Detector
Paste your essay below and get a probability score that estimates how likely a detector is to flag the text as AI-generated. The score is a guide for revision, not a verdict on you as a writer; detectors false-positive on real human writing all the time, and the right response is almost never to write worse.
Free for short texts. For long pieces or repeated checks across a class, sign up for the full essay-craft toolkit (coming soon).
How to use this
Paste your own writing.
The longer the sample, the steadier the estimate. Aim for 150 words or more so the tool has enough to read.
Read the score as a signal.
Treat the number as information about style, not a verdict on authorship. A high score is a prompt to look closer, nothing more.
If you wrote it, keep your drafts.
If your own work scored high, save your draft history and read the Authenticity Rewriter guide before you change a single sentence.
