What is Moises?
Moises is the go-to app for musicians who want to “disassemble” songs with AI: it splits any track into stems (vocals, drums, bass, guitar, the rest), changes key and tempo, and detects chords in real time. What used to require a studio and hours of work happens here in minutes from your phone or browser.
More than a stem splitter, Moises is a music practice app: mute the instrument you play and rehearse with the original track’s “band” behind you.
Who is Moises for?
- Musicians rehearsing: remove the bass, guitar or vocals from the original and play that part yourself.
- Singers: instant instrumentals of any song to practise with (serious karaoke).
- Music teachers preparing material by isolating parts.
- Producers and the curious studying mixes by hearing the layers separately.
Core features
- Stem separation with best-in-class quality: vocals, drums, bass, guitar and more.
- Key and tempo change without wrecking the audio: adapt any song to your voice or level.
- Chord detection on the fly, aligned with playback.
- Smart metronome and count-in built for rehearsal.
- Mobile and web with your library in sync.
Real-world use cases
- The bassist without a band: mute the song’s bass and rehearse with the “real” rest of the group.
- The song that sits too high: drop it two semitones and practise in your range.
- Learning a song by ear: detected chords + isolated vocals = transcription in half the time.
Pricing and plans
Moises has a free plan with limited monthly separations and basic features, and Premium by subscription with more separations, more stems, better export quality and advanced features. Current prices on their site.
Moises vs. alternatives
Against one-click separation websites (LALAL.AI and similar), Moises wins as an integral practice tool (key, tempo, chords); if you ONLY want the separated file with maximum privacy, the open-source Ultimate Vocal Remover on your machine is the free alternative. The full picture: separate vocals from music with AI.
Pros and cons
- ✅ Top-tier separation + practice tools in one app.
- ✅ Key/tempo change is gold for singers and rehearsals.
- ✅ Works on mobile and browser with a synced library.
- ❌ The free plan runs short if you separate daily.
- ❌ Publishing remixes of copyrighted songs still needs a licence (as with any tool).
Our verdict: when to use Moises (and when not)
If you play or sing, Moises is one of those apps that changes how you rehearse: the infinite backing band. If you just need one acapella extracted, a one-click site or free UVR will do. And remember: personal use is fine; publishing material from copyrighted songs needs a licence.
Frequently asked questions about Moises
Is the separation really good?
On modern, well-mixed songs, yes: vocals and instruments come out surprisingly clean. On old or saturated recordings audible remnants can remain, as with all AI separation.
Can I use the separated stems in my videos or remixes?
For practice and personal use, yes. To publish or monetise content using copyrighted songs you need the corresponding licence: separation grants no rights over the work.
