Muse Forge

Muse Forge is an AI music studio for people who want to play, remix or study a song — not just listen to it.

Upload a track and Muse Forge does the listening for you: pull it apart into separate stems, read out the chord chart, or turn it into piano sheet music you can actually follow. Or start from nothing and generate a new track from a written prompt.

WHAT YOU CAN DO

Stem Separation
Split a song into vocals, drums, bass and other tracks. Play each stem on its own, mute what you don't need, and download the ones you want.

Chord Recognition
Get the full chord progression along with the detected key and tempo. Follow a synced chart while the song plays, transpose to any key, and read guitar and ukulele fingerings.

PopPianoAI
Turn a song into a piano arrangement and read it as sheet music — in portrait, or full-screen landscape when you want to prop the phone on the piano. Export as PDF, MIDI or MusicXML to open in your notation software.

Music Generation
Describe the mood, style or instrumentation you want and get an original track back — usually in 30 seconds to 2 minutes. No upload needed.

Forge
One upload, the whole pipeline. Pick a template — for example, strip the vocals from a song and turn the accompaniment into a piano score — and get a finished result in one step, with PDF and MIDI downloads.

SUPPORTED FILES
MP3, WAV, FLAC, OGG, AAC, M4A, OPUS and WebM, up to 100 MB per file.

SUBSCRIPTIONS
Muse Forge is free to download and comes with a monthly allowance of processing time. Starter and Creator add more processing seconds each month; the allowance is shared across music generation, stem separation and chord recognition. Piano sheet music is free and does not use your allowance. A subscription also unlocks lossless downloads.

Subscriptions renew automatically. You can manage or cancel them in Google Play at any time.
