Moises.ai Review

Moises (moises.ai), from Moises Systems, Inc., is built around AI stem separation: you upload an audio or video file (MP3, WAV, FLAC, AIFF, MP4, MOV or WMA) and it splits the song into parts such as vocals, drums, bass, guitar, piano, keys, strings and winds. Moises says it offers 27 stem types, including lead and backing vocals, male and female vocals, acoustic and electric guitar, and individual drum parts (kick, snare, toms, hi-hat, cymbals), with a faster Standard model and Hi-Fi models for cleaner results. Stems export as MP3, WAV, FLAC, M4A or OGG. Around separation sit practice tools: chord detection at three difficulty levels, BPM and key detection, a smart metronome that follows the song, speed and pitch changers, AI-detected sections for looping, lyric transcription (English, Spanish, Portuguese, French and Italian per the App Store listing) and mastering by reference. Your account works across the web app, desktop apps for macOS and Windows, iPhone, iPad and Android, Apple TV and Android TV, a VST plugin and a Fender Studio Pro extension. The newer Moises Studio adds a browser-based, real-time collaborative session: multitrack recording, stem generation in 55+ genre presets (audio or MIDI), voice conversion using a library of paid session singers or a private model of your own voice, auto-mix, one-click mastering and an assistant called Moi that edits the project from plain-language requests. Moises says it never trains its models on your uploads and trains only on licensed material. Businesses and developers are sent to its sister company Music.AI for API access.

Moises has three plans: Free, Premium and Pro, billed monthly or yearly. Its web pricing page (studio.moises.ai/pricing) only shows prices after you log in, and the moises.ai FAQ says the same. The only prices Moises publishes without an account are its in-app purchase prices on the US App Store:

On the App Store, Premium is also sold yearly at $39.99/year, which works out to $39.99 / 12 = about $3.33 a month, 44% less than paying $5.99 monthly for 12 months ($71.88). The listing does not show a yearly Pro price. Other details from Moises' help center: Free uploads are counted per calendar month, so deleting a file does not free a slot. Free accounts' files are deleted after 2 months without a login. AI Studio credits each cover 30 seconds of generated audio (a 35-second clip uses 2), and unused free credits expire monthly. Subscriptions renew automatically; cancel at least 24 hours before renewal. Business and API use is priced separately through Music.AI (contact sales). Web checkout prices are shown only after you sign in and may differ from the App Store prices above.

Prices checked on the vendor's pricing page on November 10, 2026. Moises' web pricing page requires a login, so the figures above come from Moises' own App Store listing (US prices) and plan limits from the Moises help center.

What Moises' own pages and help center list:

Moises suits musicians who practice and rehearse with recorded songs: guitarists, bassists and drummers who want to mute their own part, singers who need a karaoke track in a different key, and teachers building backing tracks. The mobile apps carry most of the practice tools, and the free plan is enough to try a few songs a month. Producers who need clean stems for remixes or sampling will want Pro for the Hi-Fi models, at a much higher App Store price than Premium. If you only need occasional high-quality stem files and no practice tools, a pay-per-use separator such as LALAL.AI may cost less. If you are comfortable with desktop software and want to pay nothing, Ultimate Vocal Remover is free and open source. For chords alone, Chordify is built specifically for play-along chord charts.

On the US App Store, Moises shows a 4.7 rating from about 28,000 ratings and an Editors' Choice badge. Trustpilot tells a different story: a 1.9 TrustScore from 66 reviews, most of them complaints about being charged after cancelling, refunds and slow support, plus some about separation artifacts and unreliable chord or tempo detection. A review by StemSplit, a competing stem separator, rates Moises 4 out of 5 and best for practice tools in one app, but ranks its separation below its own product and LALAL.AI on a single test song. The practice features get the most consistent praise across these sources; billing and cancellation get the most consistent criticism.
