Real-time jamming with AI

Lead the way and the AI follows. Chase the happy accidents and build them into something worth keeping.

Fully local

Runs completely on your Mac, offline. No audio, no playing, no data ever leaves the machine.

Any instrument in the world

Type in any instrument you can imagine and the AI becomes it — mid-jam, without breaking the take.

Instruments and MIDI

Sing, play an instrument, or jam with your MIDI keyboard. No hardware? The computer keyboard works too.

Record every idea

Capture clips as you go and keep them as inspiration for your own compositions.
