StemGrab is an independent tool built and maintained by a small team. We run our separation model on our own GPU hardware to split any song into up to seven stems — vocals, drums, bass, guitar, piano, other and a clean instrumental — free, with no account required and no watermark. Files are deleted the moment processing finishes.
StemGrab is part of the ShinobiTools suite of free AI-powered tools.
Bug report: describe what you uploaded (format, length), what you expected, and what happened instead. A browser console error message or screenshot helps us fix it faster.
Feature request: describe the use case — what you were trying to do and why the current tool didn't cover it. We read every suggestion.
Question: check the FAQ on the home page and the how-it-works guide first — most common questions are answered there.
Mail [email protected] directly rather than using the form below — that way we can actually reply. Include the order number from your Polar receipt; it's the only thing that links a payment to a pass, because we deliberately don't store names or e-mail addresses.
The two things that go wrong most often, and what we do about them:
"I paid but I don't see a pass." Reload the page in the browser you bought it in — the pass is picked up on its own within a minute or two. Still nothing after that: mail us with the order number and we'll issue a fresh pass.
"My pass is gone." A pass lives in the browser you bought it in and nowhere else. It doesn't travel to a second device, and clearing your site data removes it. If that happened while your 30 days were still running, mail us with the order number and we'll put it back.
Your 30 days start with your first track, not when you pay — so there is no rush to use a pass the same evening.
We aim to reply within 1–3 business days when an e-mail address is provided. Messages without an e-mail are read but cannot be answered individually. Anything about a paid pass gets an answer within 48 hours, and if we can't fix it we refund you.
