There is no support desk behind this site — just one inbox. A person writes back.

• Report a separation problem — tell us the song and genre (vocal-heavy or instrumental?), which tool you used, and which stem came out dirty. A short clip of the original helps.
• Report a browser problem — if the page does nothing at all, include your browser version (e.g. Chrome 130, Safari 18).
• Suggest a new tool — want something that is not here yet? Tell us what you would use it for; that is more useful than the tool’s name.

Note: this site has no upload endpoint, so we never receive your audio — and never need it. Describe the problem instead of attaching the whole song.
