Tool comparison
VocalSplit vs StemRoller
StemRoller is a free open-source desktop app that wraps Demucs in a simple GUI. It is great on a fast PC. VocalSplit is a hosted alternative that sidesteps the download-model-then-wait workflow entirely.

Why VocalSplit wins for most people
VocalSplit runs in 15 seconds regardless of whether you are on a top-spec desktop or a cheap Chromebook. No install, no model download, no waiting 1–5 minutes while your laptop fan spins up.
What VocalSplit gives up
VocalSplit uploads audio to our servers (stored 24 hours, then deleted). For workflows that require 100% local processing — strict privacy rules, sensitive material — StemRoller runs Demucs on your own machine without any network round-trip.
Our take: StemRoller is great if you have a fast PC and don't mind the install. For everyone else, VocalSplit is faster, simpler and device-independent.
