98.2%of tracks from known generators are caught

1.5%of human tracks are wrongly flagged

84.0%even on generators we have never seen

29.0%of edited AI tracks slip through

Suno 8/8 · Udio 12/12 · Riffusion 13/13 — 98.2% across 111 tracks from generators we train on. That is exactly the condition the industry quotes. The other three are the numbers most detectors leave out — and without a false‑positive rate a detection rate cannot be compared at all, because dropping the threshold raises it as far as you like. How we measured this · Every limit

Answers come in two grades

Grade A

The file itself declares a generated origin. A fact anyone can re‑verify by opening it.

Grade B

A judgement from the audio alone. Less certain the more the track has been edited.

A verdict is evidence, not proof. That a human made a recording is something no detector can prove.

Whole catalogs too

12,480 tracks takes about 4.0 hours. Send a list of URLs or a CSV, get a CSV back. A track that cleared two years ago may not clear today — rescanning is the point.

What we do not do

We do not analyse video or speech. We cannot tell you which tool made a track unless the file says so — naming it from audio alone is something we have not measured, so we do not sell it. And we will not build the inverse product that helps AI tracks slip past someone else's screening.
