A Moises alternative
Moises separates stems in the cloud on a subscription. Beltr does its AI vocal separation on your own computer — nothing uploaded, no monthly bill — then turns your songs into a full karaoke night. One-time $19.99. Here's the honest side-by-side.
Beltr is a one-time $19.99 desktop app that separates vocals on your own computer with on-device AI — nothing is uploaded. Moises is a subscription cloud app ($5.99/month or $39.99/year, Pro $29.99/month) that uploads your track to its servers and is built for musicians who want stem isolation and practice tools. Both work on songs you already own. Choose Beltr if you want to pay once, keep everything private on your machine, and get a complete karaoke setup. Choose Moises if you're a musician who wants cloud stem tools synced across your devices.

Why people choose Beltr
The four reasons home singers reach for Beltr instead — and how owning your setup delivers each one.
Moises processes in the cloud, so your track goes to its servers. Beltr runs its AI on-device — your audio never leaves your machine. No uploads, no cloud queue.
Subscriptions keep billing whether you sing twice a year or never. Beltr is one payment. Host karaoke at New Year's, forget about it until next year — no charge waiting for you.
Cloud processing leans on your connection to upload and separate every track. Beltr separates vocals and plays entirely on your computer — nothing to upload, nothing to wait on.
A stem tool hands you separated audio to work with. Beltr goes further: synced lyrics on your TV, phones as remotes, and live pitch scoring — a whole party from the songs you own.
More than a stem tool
A stem separator gives you audio files. Because Beltr runs on your computer, it turns your living room into the stage.
Big, readable, word-synced lyrics on the main screen so the whole room sings along.
Guests scan a QR code to queue songs and run the room from their phones — no app install, no logins.
Score singers in real time for a game-night feel, or keep it casual — your call.
Beltr films the performance and drops a vertical clip on your phone — made on your machine, shared only when you tap.
Being fair
We'll be straight with you: Moises is a great product for a different job. If you're a musician who wants clean stem isolation, chord and section detection, speed and pitch practice tools, and everything synced across web, desktop, and mobile in the cloud, Moises is purpose-built for exactly that — and it's excellent at it.
Beltr is for the other kind of person: someone who wants to sing their own songs, own their setup with one payment, keep everything on their own computer, and turn it into a real karaoke night. If that's you, read on.
