Was this written by AI or by a human?
Paste text, an image, audio, video or a website. We run a forensic analysis and show how 15 well-known AI detectors would most likely rate the same content — free, with no AI credits used.
How it works
One score, and the full spread behind it
Paste or upload
Text, an image, an audio file, a video or a website URL — five content types in one console.
We measure 8 signals
Burstiness, predictability, lexical diversity, phrase patterns, punctuation, voice, repetition and rhythm.
15 detectors compared
See the spread across the best-known detection services instead of trusting one single number.

The 15 detectors we calibrate against
Every service has its own threshold and its own focus. We model how they typically react to the signals we measure, so you see the spread instead of a single number.
