Karaoke StarSinger takes an audio or video file that you upload and returns a karaoke version of it: the vocal separated from the instrumental, the lyrics written with the timing of every syllable, and the pitch of every note. Nothing else.
We have no catalogue. We do not search for, host or distribute music. If you do not upload a file, there is nothing to sing. Your library is yours alone — no other user can reach your files.
You confirm you have the right to use what you upload — because it is yours, because you bought it, or because the law allows the use you intend. Private use of a copy you own is not the same as public performance; that is on you, not on us.
One person per account. Keep your password — whoever has it gets in. If you suspect someone else got access, change it: changing the password ends every open session, including theirs.
Each plan has a limit of songs per month and of disk space. The limits show up in your account and exist for a practical reason: separating vocals from instrumentals is expensive to compute, and without a limit a single account would take the service down for everyone else.
Vocal separation, lyric transcription and note detection are done by machine. They get things wrong. Songs with heavy reverb, choirs, muffled vocals or poor recording come out worse. The service is provided as is — we promise no specific accuracy.
We may go offline for maintenance or because of a failure. We give notice when notice is possible. If you pay and the service stays unavailable for a long stretch, talk to us.
You can delete the account whenever you like. When you do, your files and your library go with it, and there is no undo.
If we change anything material, the date at the top changes and we tell you by email.
