How it works
Three steps to a confident release.

No jargon, no legal database to search yourself. Upload, wait two minutes, get a verdict you can act on.

01
Upload your track.

Drop an audio file — MP3, M4A, WAV, OGG, or FLAC up to 25MB. However you made it, if you can export it as an audio file, Safi checks it. No audio yet? Paste lyrics alone for a text-only pass.

  • Safi checks the file, not the platform
  • Files are deleted after analysis by default
  • Your music is never used to train any model

02
Safi scores everything.

Your track is checked across four dimensions: lyrics, melody, structure, and vocal style. Each returns a 1–10 similarity score. A dimension Safi can't assess — Voice, with no audio supplied — comes back unscored, never clean.

03
Get your verdict.

Every check returns one of four fixed verdicts. There's no fifth "safe" tier — Safi screens for similarity, it doesn't clear anything.

MODERATE RISK — MODIFY BEFORE RELEASE

Flagged: structure, verse 2. A moderate verdict is a signal to revise the flagged section, not a legal determination.
