A Splitter.ai Alternative That Never Uploads Your Song
Splitter.ai is one of the earlier web services for AI stem separation. The workflow is upload-based: your song goes to their servers for processing, and you download the split results.
LA Studio's splitter uses AI too (Demucs v4 / HTDemucs) — but runs it entirely in your browser. The song is never uploaded, the six-stem split (vocals, drums, bass, guitar, piano, other) is free, and instead of ending at a download, the stems land on tracks in a browser DAW where you can keep mixing, adding effects and exporting.
Everything runs in your browser — your audio is never uploaded.
What Splitter.ai does well
In fairness: the upload model has real advantages. Because processing happens server-side, your device's horsepower doesn't matter — an old laptop or a phone gets the same result as long as it can upload. And the hand-it-over-and-wait workflow means there is nothing to learn.

When you should still pick Splitter.ai
If your device is too low-powered to run an AI model in the browser, a server-side service is the right call. Pick LA Studio if you want your audio to stay on your machine, want guitar and piano separated too, or want to keep mixing, tuning and exporting after the split — try one song free and compare with your ears.

Frequently asked questions
Does it really split without uploading?
Yes — the Demucs v4 model downloads into your browser and the separation runs on your device. The song never reaches a server.
How much is free?
The 6-stem split, full-length WAV export and DAW editing are free. Only the higher-quality cloud separation (HQ vocals) is Pro.
Is the quality equal to server-side services?
The in-browser Demucs-family model is strong for a free tool, though large server-side models can win on some material. Trying free first costs nothing.
How long does it take?
Depends on your device. The first run includes the model download, so it's slower; later runs are faster.
Do I need an account?
No — only cloud save (5 projects free) needs one.
