Moises is an AI musician's app that separates any song into stems (vocals, drums, bass, guitar), detects chords and key, syncs a smart metronome, and transcribes lyrics for practice, rehearsal, and performance.

Overview

Moises is an AI app built by musicians for musicians, and it has become the default pocket toolkit for practice, rehearsal, and performance. Its core engine, Orchestrator, separates any song into stems — vocals, drums, bass, and guitar — so a student can mute the guitar and play along, or a producer can lift a clean vocal for a remix. From there it layers the tools players actually open mid-session: chord detection with a synchronized chord grid, a smart metronome that locks to the recording (the first of its kind), key and BPM detection, pitch shifting to slow a song down for practice, and AI lyric transcription. The catalog spans iOS, Android, and web, and the company reports more than 30 million users plus an iPad App of the Year 2024 award, with endorsements from working drummers and educators. In our evaluation the stem separation is best-in-class for everyday use and the smart metronome alone is worth the install for rehearsing bands. The honest limits are real: densely layered or low-bitrate mixes can leave residual bleed between stems, and the highest-fidelity models, advanced instrument splits, and Voice Studio sit behind paid tiers. Cloud processing also needs a connection. Used as designed — clean stems and practice tools on a phone — Moises is the closest thing to having a full band in your pocket, and the free tier is generous enough to judge it before paying.

Comparison

Compared to LALAL AI, Moises separates stems too but wraps them in a full practice suite — chords, smart metronome, pitch shifting — rather than standing alone as a separation utility. Against Cleanvoice, the difference is music versus speech: Cleanvoice polishes podcast dialogue (fillers, mouth clicks), while Moises targets songs and instruments for musicians. For AI music generation rather than separation, Suno is the creative counterpart in the same audio category.

Pros
  • +Best-in-class stem separation lets you isolate vocals, drums, bass, and guitar for practice or remix
  • +Smart metronome locks to the song and a chord grid shows in real time — a rehearsal game changer
  • +Generous free tier plus 30M+ users and iPad App of the Year 2024 credibility
Cons
  • Dense or low-bitrate mixes can leave bleed between stems — not forensic-grade isolation
  • Hi-Fi models, advanced splits, and Voice Studio require paid Premium or Pro

Moises is the closest thing to carrying a full band in your pocket. For students, teachers, and working musicians the stem separation and smart metronome alone justify the install, and the free tier is genuinely usable. Cloud processing needs a connection and the very best separation is paywalled, but within its lane it is the category leader and we rate it highly.
