About
Suno Checker tells you whether a track shows signs of AI generation. Drop in an MP3, WAV, FLAC or M4A file (15 seconds to 10 minutes), record the audio playing on your computer, or paste a public SoundCloud link.
When a track reads as AI, Suno Checker scans the whole song in overlapping ten-second windows and marks the sections where AI signals appear, so you can see whether a song is AI from start to finish or only in parts. When the signals warrant it, it also estimates the source: a Suno version (v2 to v5.5) or Udio.
Everything is free, with no account and no track quota, and you can export results as CSV. Your original file never leaves your browser, and no audio or results are stored.
A score is a model estimate, not proof of authorship or copyright clearance. Suno Checker is not affiliated with Suno or Udio. It is made by fromband.
