AI stem splitters and mastering services: what they cost and what their terms say about your audio (tracker)

A living table of the prices and terms for LALAL.AI, Moises, LANDR, BandLab, iZotope Ozone and Ultimate Vocal Remover: what you pay, what the limits are, who owns the output and whether your uploads can train AI. Each row cites the page we read and the date we read it.

Key facts

  • LALAL.AI Pro costs $15 a month or $180 a year for 250 fast-queue minutes, and splitting into several stems uses up minutes for each stem.
  • Moises terms say it will not use your uploads or output to train AI unless you opt in, and they let you use output commercially inside a finished track but not sell it as samples.
  • Ultimate Vocal Remover is free and open source under the MIT licence.

This is a living table of what the main AI stem splitters and mastering services cost, and what their terms say about the audio you put in and get out. It answers four questions for each tool: what you pay, what the limits are, who owns the result, and whether your uploads can be used to train AI. Every row cites the page we read and the date we read it. Where a page didn't say, we say so.

"Doesn't say" means we couldn't find it on a page we read. It doesn't mean the answer is yes or no.

What the table shows

Minutes are the real price on stem splitters. LALAL.AI charges file length times the number of stem types you pick. On our reading, a four-minute song split into five stems uses 20 minutes, so Pro's 250 fast minutes cover about 12 such songs a month. If you split whole albums, the per-minute maths matters more than the headline price.

The terms differ more than the prices. Moises and LANDR both say plainly that they won't train on your uploads without an opt-in. LALAL.AI's terms say nothing on ownership or training and put all the responsibility on you. For a musician sending unreleased masters to a web service, that difference is worth more than a few dollars a month.

Local tools sidestep the question. Ozone and UVR process audio on your own machine, so there is no upload to license or train on. UVR is free. If your material is sensitive, a local tool is the cautious choice, at the cost of setup and computer time.

What we think

Read the terms before the price. A stem splitter is cheap, but your unreleased song is not, and the pages that answer the training question in plain words deserve your files first. We'd like every service in this table to state output ownership and training use on its pricing page, not deep in its terms. We'll update the table when they change.
