Moises

Moises is a mobile-first app for musicians that combines AI stem separation with practice tools including tempo change with pitch lock, key and chord detection, a smart metronome, section looping, and lyric transcription. It is the leading choice for cover artists, students, and gigging musicians who practice and play along. For maximum studio-grade stem fidelity, dedicated desktop tools may still edge it.

Moises, made by Music AI, is built specifically for the way musicians practice and rehearse. Its foundation is AI stem separation, letting you split any song into vocals, drums, bass, guitar, keys, and other parts so you can mute an instrument to play along, isolate a line to learn it, or build a backing track. On top of that it layers practice-oriented features: tempo change with pitch lock, key and chord detection, a smart metronome with chord tracking, a section looper, and lyric/chord transcription. What sets Moises apart from pure separation tools is its mobile-first design and practice workflow. It is widely regarded as the strongest option for cover artists, students, and gigging musicians who want to slow down a track, transpose it to a comfortable key, and loop tricky sections, all from a phone or tablet. The app was named Apple's iPad App of the Year in 2024 and reports a very large user base, reflecting real traction among everyday musicians rather than only producers. Moises uses a freemium model: a free tier with a small monthly upload allowance and basic stems, a mid Premium tier that unlocks more uploads and the tempo/pitch tools, and a Pro tier with unlimited use. Because it is designed around practice rather than studio-grade production, some producers still prefer dedicated desktop separators for the highest-fidelity stems, but for learning and playing along Moises is hard to beat.
