Fine print
Answers before you ask.
Is this really free?
Yes. 3 jobs per 24 hours per IP. If you need more, that's usually a sign you should be running Demucs locally.
What happens to my files?
Input and output are both deleted automatically 15 minutes after the job is created. No analytics, no retention.
Can I use this commercially?
Only on material you have the right to process. Don't upload copyrighted content you don't own or have rights to split.
Why aren't YouTube URLs supported?
This is a public service. YouTube URL ingestion is kept off the public surface to avoid abuse. Bring your own file.
