The bottom line: Moises’ free plan gives you 5 AI stem separations a month — split any song into vocals, drums, bass, and more — plus a free pitch and tempo changer, key/BPM detection, and practice tools. The catches: 5-minute track limit, basic separation quality, and an account is required. It’s a genuine free tier for musicians learning songs, not a production tool.
What is Moises?
Moises is an AI app for musicians that separates any song into individual stems — pull the vocals out of a track, isolate the drums, mute the bass so you can play along. On top of separation it layers practice tools: a smart metronome, pitch and tempo controls (slow a solo down without changing its pitch), chord detection, and lyric transcription. It runs on web, iOS, and Android.
The free plan is a real ongoing tier — 5 separations a month, every month — aimed at musicians practicing, not producing.
What’s actually free
The Free plan ($0) includes:
- 5 AI audio separations per month — split songs into vocals, drums, bass, and other stems
- Free pitch & tempo changer — slow down or speed up any track, change its key
- Key and BPM detection on every upload
- 60 generative-AI credits for AI stem generation experiments
- Chord detection and smart metronome basics for practice
Five songs a month is enough to learn a setlist piece by piece — upload this week’s song, isolate your instrument’s part, slow the hard section down, learn it.
What’s behind the paywall
The free tier has firm boundaries:
- 5-minute track cap: longer tracks get truncated — most live recordings and long jams won’t fit.
- Standard separation quality: the high-fidelity models are paid; complex mixes may have more bleed-through on free.
- Basic stem types: separating guitar, piano, and drum sub-parts needs paid plans.
- Account required: you must sign up with an email before processing anything.
- No commercial use: stems from copyrighted recordings are for personal practice only.
Moises Premium costs $3.99/month (around $36/year billed annually) — unlimited separations, all core stem types, 20-minute uploads, no ads. Moises Pro at $9.99/month adds Hi-Fi models, lossless exports, and VST plugins.
Who it’s best for
Moises’ free tier is best for guitarists, drummers, singers, and music students learning songs by ear: isolate the part you need to learn, slow it down, loop it. Cover bands building backing tracks and karaoke fans also get real value from 5 free separations a month.
It’s not for producers exporting stems into a DAW, remixers, or anyone processing long recordings — the track cap and quality ceiling push those users to paid.

Frequently asked questions
Is Moises free?
Yes — the Free plan costs $0 and includes 5 AI audio separations per month, a free pitch and tempo changer, and key/BPM detection.
How many stems can the free plan separate?
The free plan separates the standard core stems (vocals, drums, bass, and others). Finer splits like isolated guitar, piano, and drum parts require a paid plan.
Can I use Moises stems in my own music?
Only if you own the rights to the original recording. Extracting stems from commercial songs for your own releases without permission is copyright infringement — the free tier is meant for practice.
Does Moises work on phones?
Yes — Moises has native iOS and Android apps with the same features as the web version.
Verdict
For musicians who learn by ear, Moises’ free tier is one of the best deals in music software: five songs a month, isolated and slowed down, for zero dollars. It’s a practice tool that happens to be free — and at $3.99/month, the upgrade is painless when you outgrow it.
