About Moises
Moises is an AI music app that separates any song into isolated stems such as vocals, drums, bass, guitar, and keys, then wraps them in practice tools like chord detection, speed and pitch control, and lyric transcription. It runs in the browser, on desktop, and on iOS and Android, and adds Moises Studio for real-time collaborative recording and arranging in the browser.
Pros & Cons
Pros
- Stem separation is paired with practice tools (chords, tempo, pitch, metronome, lyrics), so musicians don't need a separate app to learn a song
- Wide stem coverage, up to 27 stem types, beyond the usual vocals/drums/bass/other split
- Available on web, desktop, iOS, iPad, and Android with a synced library
- States it never trains models on user uploads and trains only on licensed material
- Free tier allows testing without a credit card
- Strong app store standing: 4.7 stars from about 28K ratings on the US App Store
Cons
- Full pricing table is only visible after login, and prices differ between the web and app stores
- Free tier caps monthly uploads, which limits regular practice use
- Pro is expensive at $29.99/month on the App Store compared with Premium
- Some bleed between instruments on dense mixes, as with most AI separators
- Cloud processing means uploading source audio to a third party
