How it scores

Usefulness
3/5

Reliable practice tool for musicians (Music Connection musicconnection.com/new-toys-moises…; Violet Recording violetrecording.com/moises-review), but a narrow job for most people and user reviews says free splitters like MVSep can beat it.

Ease of use
4/5

Phone, web and desktop apps; Music Connection calls the layout 'sleek and minimal'; user reviews reports silent failures with no error messages.

Value for money
4/5

Free tier covers basic splits; Premium £4.99 a month is below the £8-£20 peer range (apps.apple.com/gb/…/id1515796612); Trustpilot 1.7 from 65 reviews cites refunds and cancelling (trustpilot.com/review/moises.ai).

Privacy and trust
4/5

FAQ says it never trains on user data and uses licensed training material (moises.ai/pricing); no incidents found; policy allows interest-based advertising partners (moises.ai/privacy).

Momentum in 2026
4/5

a16z 7th-edition revenue list #48; Charlie Puth named Chief Music Officer in March 2026 with 70 million users claimed (musicbusinessworldwide.com); new Moises Studio launched September 2026 (youtube.com/watch?v=U9s7RrTKCUo).

Verdict

Moises takes a recording and pulls the instruments apart, then adds chord charts, a click track and key and speed changes for practice. Premium costs £4.99 a month in the UK App Store, cheaper than most AI subscriptions, and the company says it never trains on user uploads. Drummers in user reviews say processing has slowed and better separation now sits behind the £24.99 Pro plan.

Ratings

What people say

Musicians who use it for practice say it does the job, but 2026 user threads complain about slower processing, silent failures and the best drum splits moving to the pricier Pro plan, with some saying free or credit-based splitters such as MVSep separate better. Store stars (4.63 iOS, 4.4 Play from 434,561) sit well above Trustpilot's 1.7 from 65 reviews, which centre on refunds and cancelling.

“Just released! @moises_ai AI stem generator on mobile! No laptop. No studio. Just you and your phone. … It's really amazing!”

“I have the premium (I think, was around $40 for the whole year). Works for me as is.”

Individual user review, 11 March 2026 · source

“now the processing time has increased significantly, and they started a new plan "Pro" … it's also $20 per month, and I feel a bit fooled that my Premium subscription is only second-class”

Individual user review, 11 March 2026 · source

“if something goes wrong, I never get a helpful error message. Instead, the app fails silently or even seems to be processing the song but never gets to an end.”

Individual user review, 11 March 2026 · source

“MVSep absolutely wipes the floor with Moises. … forget about clean vocal separations.”

Press reviews

  • Music Connection 2025-06-26

    Separation is 'fast and yields very good results' and the interface is clean; 'a genuinely useful tool for practicing, remixing, and experimentation'.

  • Music Teacher (UK) 2024-08-01

    Classroom-focused review by Tim Hallas: stem splitting is the flagship and worth having for teaching; other features matter less.

  • Violet Recording 2026-06-03

    'The best all-in-one pick for practising musicians'; separation is solid on modern mixes but dense or lo-fi tracks leave artefacts and bleed.

FAQ

Is Moises free?

Yes, with a limited number of uploads a month and basic vocals, drums and bass separation. Premium is £4.99 a month in the UK App Store and Pro is £24.99.

Does Moises use my songs to train its AI?

Moises says it will never train on user data and trains only on licensed material. Its privacy policy does not mention model training either way.

Can Moises take songs from YouTube or Spotify?

A 2026 user thread reports the app now rejects links with 'Files from streaming services are not supported'. Uploading an audio or video file, or picking from the phone's music library, still works.

Is Moises good enough for releasing remixes?

Reviewers say it is built for practice. Dense or lo-fi tracks leave artefacts and bleed, and some individual reviewers prefer dedicated splitters for clean vocals.

Does Moises make songs like Suno?

No. Moises separates and reworks existing recordings and can add AI backing parts, but it does not generate whole songs from a prompt.
