Be your own band
AI stem separator and practice studio for musicians
Jambox is an AI stem separator that pulls any song apart into vocals, guitar, drums, bass, and piano, with chords, key, tempo, and lyrics. Mute your part, step in, and record your take. Then another. Slow the tricky bars to a crawl until they’re yours. Then play it like you wrote it.
The jam place
Every part on its own lane, the chords above them, and the bars you are drilling looped on the ruler.
The library
Drop in a file and it comes back as five parts — key, tempo, chords and lyrics already read.
Record your own part
Record your vocal or guitar over the song, take after take.
The three that have to be right
Five-stem separation
Five parts from one file — guitar, drums, bass, vocals and piano — pulled apart cleanly, in one pass.
Chords by JamAI
JamAI, our own chord-recognition engine, reads the progression and keeps it in sync with the song.
Private by design
Audio, stems and chord charts never leave your computer. Nothing is uploaded — the analysis happens on your machine.
