Moises: reviews and analysis

TLDR: Moises splits a song into tracks and then lets you work them inside the app, with key, tempo, metronome and reference mastering, across web, mobile and desktop. It starts from $0, with the free tier capped at five monthly files of five minutes on basic models. The price of the paid plans is not published in the open, which is worth knowing before you spend time trying it.

What Moises is and how it works

Almost every tool in this category shares the first step: upload a song, a model separates the sources, you get a folder of files back. What sets Moises apart comes afterwards, and it has a lot to do with where you can do it.

The separation covers what a musician expects. The official product page describes isolating lead and background vocals and extracting guitars, bass, drums and other instruments, with building acapellas and karaoke from the original as an intended use. Quality and the number of separable parts change by plan.

On top sits a practice layer. The system detects tempo and key, so you can drop the key to sing in your range or slow the tempo to learn a solo. There is a metronome, and the click can be included in the export, which means you pull out a practice track that is already aligned. Export comes as MP3, M4A and WAV. There is also reference mastering, nudging your mix towards the sound of a song you give it as a model, though that function scores below the rest in our capability assessment and does not justify the purchase on its own.

The comparison needs precision, because other tools in the segment also moved past plain separation: Fadr includes remix, chords and MIDI, and RipX DAW edits audio note by note. What Moises gathers together and they do not is that practice layer with a presence on web, iOS, Android, Mac and Windows, plus a private cloud library reachable from any device. For a teacher who prepares material on a laptop and uses it from a phone in class, that continuity outweighs a point of separation quality. The rest of the category sits in the stem separation hub.

What using it is like day to day

Nobody on our team has prepared a set list in Moises, so what follows comes from the official documentation and from our catalogue assessment.

The documented path is short: upload the file, wait for processing, work on the result inside the app. Where the flow breaks is set by your plan. On the free tier that means five files a month and five minutes per file on the basic models. Five minutes covers an ordinary song and rules out a live recording, a rehearsal tape or a whole lesson. Five files a month is enough to try it and falls short of preparing a repertoire.

That carries a consequence which decides the purchase: the free tier tells you about the interface, not about the quality you would be buying. The basic models are not the paid ones. If your decision hinges on how much vocal bleeds into the drum residue, that test has to happen inside the paid plan.

When you run it, upload the hardest material you have. A heavily reverberant recording, an old mix or a live take separate one tool from another far better than a clean song does. And check on your own file whether chord and key detection get it right, because that layer is the reason you would be choosing Moises over a plain separator.

Pricing and plans

Moises is freemium and starts from $0, with a trial available on the paid side. Above the free tier there are plans that widen the models available, the length accepted per file, the number of separable instruments and the export quality, with Hi-Fi separation reserved for the top plan.

Those figures are not published in the open. The official pricing page shows no table at all, it asks you to log in to see the full pricing and features table, and it limits itself to saying that the free tier provides a limited number of uploads each month. To find out what you would be charged you have to create an account or open your store listing, and that is how the product is set up.

That opacity costs it something in the comparison. In the same segment, Fadr is listed from $10 a month and LALAL.AI from $7.5 on its annual plan, figures you can weigh before deciding. With the paid plans of Moises you have to take one more step before comparing anything.

Who it is for (and who it is not for)

It is for people who are going to do something with the tracks. A musician learning songs by ear, a teacher who builds a backing track without vocals and then slows it down in class, a singer who needs the key dropped, a drummer who wants the click aligned in the export. That profile uses the practice layer, which is what is really being bought.

Three profiles should look elsewhere. Anyone who needs one thing separated on a one-off basis, because a per-minute purchase beats a subscription there. Anyone processing high volume on no budget. And anyone who cannot upload the material to a server for confidentiality reasons, since this is a cloud service.

Alternatives to Moises

The comparisons are developed on our Moises alternatives page. In short: LALAL.AI is the convenient one for a single job, sold by processing minutes with a local plugin on its top plan. Fadr is the generous one, with unlimited basic separation on its free tier. RipX DAW is the one for control, with note-level editing and processing on your own machine, from $99 as a one-time purchase. And Ultimate Vocal Remover changes the nature of the deal: zero cost and local processing, with no support and no practice tools, and with model and parameter choice on you.

Frequently asked questions

How much does Moises cost?

The free tier starts from $0. The paid plans do not publish their price in the open: the official page asks you to sign in to see the full table, so you will need to open your store listing or create an account.

What does the free tier limit?

Five files a month, five minutes per file and the basic separation models. Hi-Fi separation and separating more instruments belong to the top plan.

Is it for practising with a song?

That is exactly what it is built for. It detects tempo and key, lets you change pitch and speed, includes a metronome and exports the tracks with the click included.

Can I work offline?

Not really. There are Mac and Windows apps alongside web and mobile, but the product is organised around a cloud library.

Which export formats does it support?

The official documentation lists MP3, M4A and WAV, with the option of including the metronome. Availability of the highest quality depends on your plan.
