Sync a song
Paste an LRC / Enhanced LRC / UltraStar file, tap out line timing with the simulator, or request an AI word-sync from a YouTube link. Every submission becomes a new revision — nothing is overwritten.
Publishing runs a ~1–2 second proof-of-work in your browser to deter spam. Submissions are anonymous; only a salted hash of your IP/browser is stored.
