Frequently asked questions

Does this use AI?

No. Notes, chords and drums come from what you edit or from fixed rules and templates.

Does audio get uploaded or saved?

No. Playback is generated in your browser. Project JSON may stay in localStorage. Raw audio is not stored.

Will this voice-lead like a pianist?

No. Each chord is a simple stack plus a bass note so you can hear the harmony.
