AI Music Detector
Drop in a song and see how likely it is to be made with an AI music generator. The check runs right here in your browser: your file is never uploaded.

Part by part
Each part of about 30 seconds is checked on its own. Short parts give a rougher read than the whole song.
How it works
The fingerprint
Music generators like Suno and Udio build the sound with a neural vocoder. The way it rebuilds the audio leaves small, regular peaks in the 1 to 8 kHz range that people do not hear. The detector averages the whole song's spectrum, keeps only those peaks, and a trained model turns them into a likelihood.
What the number means
It is how likely the whole song is to be AI generated, from 0% to 100%. Above 50% it is counted as AI. It is not a measure of how much of a song was made with AI; the part by part view shows which sections carry the fingerprint. More about AI labels
Know its limits
It was trained on Suno (up to version 5) and Udio (up to 1.5). Other or newer generators, heavy mastering, re-recording or very low quality files can hide the fingerprint, and no detector is right every time. Treat the result as a strong hint, not proof.
