Moises Studio goes browser-native: a collaborative AI workspace with an agent built in

Moises, best known as the app people use to pull vocals or drums out of a song, launched Moises Studio on 2 Sep 2026: a full music workspace that runs in the browser, with several people able to work in one session at once. In the months around it, the company also put its tools inside Fender Studio Pro 8.1, Universal Audio's LUNA and SoundCloud. A browser DAW with an AI assistant attached is now a category, not a novelty, and Moises is trying to be both a workspace and the AI supplier to other people's workspaces.

What's in Moises Studio?

According to the launch announcement, Studio covers:

• Recording and MIDI in a shared session, with live cursors, timeline comments and link sharing. Moises says MIDI controllers and VST collections will be supported.
• Generated parts, not songs. Studio adds drums, bass, guitar, keys, strings and other parts matched to the project's key, tempo, genre and instrumentation, and each part stays editable. Transcription turns recorded and generated audio into MIDI.
• Agentic Mode, which comps takes, cleans up noisy recordings and builds effect chains, with every step visible and reversible. The SoundCloud announcement names the assistant Moi.
• Custom Voice Models trained on your own recordings, private by default, alongside more than 50 licensed voices.
• Finishing and export: auto-mixing across more than 20 genres, mastering, a stem-separation upgrade covering more than 30 instrument and vocal categories, and export to mixes, stems, MIDI, MusicXML or a full session in the DAWproject format.

It's free to start, with paid plans from $5.99 a month in the US that add AI usage, storage and advanced features. Processing runs in the cloud. Moises says 80 million musicians use its products.

Where else does Moises now show up?

Three integrations in just over four months:

• Fender Studio Pro 8.1 (announced 9 Jun 2026): stem separation, vocal transformation and accompaniment generation inside the DAW, with a 14-day Moises Pro trial for Studio Pro users. Sound On Sound's review counts up to 20 instrument options with the Moises-powered separation, against four before.
• UA LUNA (22 Sep 2026): lyric transcription into a time-aligned lyric browser and chord extraction onto LUNA's Chord Track, available in LUNA Studio ($199, or included in UAD Spark Studio at $19.99 a month).
• SoundCloud (21 Oct 2026): import eligible SoundCloud tracks into Moises, work on them in Studio, and publish back to SoundCloud. Neither company defines "eligible" in the announcement.

Moises also says Ableton chose its stem separation for Live. That is Moises' claim in its own release; we haven't seen the technical details.

What do the terms actually say?

This is where Moises deserves credit, and a closer read. The terms (last updated 7 Oct 2026) say in capitals that Moises does not have the right to use your uploads or outputs to train AI models without your express opt-in. Training a custom voice or amp model you start yourself counts as opt-in for that model only. That is a contractual promise, which is stronger than a line in a blog post. SoundCloud's announcement makes a similar no-training-without-consent statement for artists' music on its side.

Three other clauses matter more day to day:

• Outputs aren't exclusive. You keep rights in what you make "to the extent allowed in your jurisdiction", but the terms warn that similar output can be generated for other users, and you can't resell generated output as standalone samples or loops.
• Storage isn't guaranteed. Moises says it has no obligation to store your content and may delete content from inactive accounts under tier-based retention rules on its pricing page. We couldn't see those rules without logging in.
• The licence you grant is broad in form but narrow in purpose. It's worldwide, royalty-free and sublicensable, but limited to processing your content and generating output for you.

Why the browser matters here

A desktop DAW keeps your session on your disk. A cloud workspace keeps it on someone else's server, under their retention policy, behind their subscription. For collaboration that's the point: nobody emails stems back and forth. But it changes what "owning your work" means in practice. Owning the copyright is one thing. Having the files is another.

DAWproject export is the most important feature on the list for that reason. It's an open session format, so a project started in the browser can leave for another DAW with its tracks and arrangement intact, rather than as a pile of bounced stems.

What we think

Moises' real move isn't the browser workspace. It's becoming the AI layer that sits inside other companies' products. Fender, UA, SoundCloud and, by Moises' account, Ableton all chose to rent its models rather than build their own. That puts Moises in an odd position: it supplies stem separation and transcription to DAWs while offering musicians a workspace that competes with those same DAWs. For now, partners seem to see it as a feature vendor. That holds as long as Studio stays lightweight. If it becomes where people finish records, those partnerships get harder to keep friendly.

For artists, the training clause is close to the standard the industry should hold everyone to: no training on your uploads unless you opt in, written into the contract. Ask every AI tool for that, not just a values page. But it's only one of three questions. The others are whether your outputs are exclusive (here, no) and whether your sessions survive if you stop paying or stop logging in (here, not guaranteed). If you work in Studio, export DAWproject files and stems of anything that matters, regularly, and keep them on your own drive.

The category is filling up. Veena is another browser DAW with an AI co-producer that builds tracks with you layer by layer, and the same questions apply to it and every other tool in this space: what trains on your work, who owns the output, and how you get your sessions out. The tools that answer all three plainly, in their terms rather than their marketing, are the ones worth building a catalogue on.
