How it works

Forensic-grade
music analysis.

Lyric scanner

Catches paraphrased hooks, verse echoes, and direct lifts using sliding n-gram windows and semantic similarity against millions of registered lyrics.

Melodic match

MIDI-extracted contour & interval comparison.

Chord engine

Detects shared progressions across keys.

Regional verdicts

Each jurisdiction has its own fair-use threshold. We render verdicts you can defend in court.

Defensible reports

Export a timestamped, signed PDF that is admissible in dispute resolution. Built for music attorneys.

Jurisdiction aware

Different country.
Different rules.

A 14% lyric overlap might be defensible in the US under Fair Use but trigger an automatic infringement claim in Japan. SonicCheck applies the right threshold for the right region.
