SonicCheck is the Turnitin for music. Drop in a track or lyrics and we score it against millions of copyrighted works, then tell you exactly what is defensible in your jurisdiction — US Fair Use, EU Quotation, UK Fair Dealing, and more.
Three engines, one verdict. Upload an audio file, paste lyrics, or both — we run them through lyric, melodic, and chord analyzers, then apply your region's copyright doctrine.
Catches paraphrased hooks, verse echoes, and direct lifts using sliding n-gram windows and semantic similarity against millions of registered lyrics.
MIDI-extracted contour & interval comparison.
Detects shared progressions across keys.
Each jurisdiction has its own fair-use threshold. We render verdicts you can defend in court.
Export a timestamped, signed PDF that is admissible in dispute resolution. Built for music attorneys.
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.
“Levitating” — 22% lyric overlap in EU jurisdiction (limit: 10%).
Built for the music industry: A&R teams, labels, producers, and the next generation of artists in conservatories worldwide.
