Free AI-powered music demixer

Effortlessly split your songs into individual stems - vocals, bass, drums, and melody - using the best and latest AI model in our free web application. It runs locally on your computer 🫵🏽, ensuring unlimited usage without any restrictions. Powered by the Demucs Hybrid Transformer AI model, created and maintained by Sevag H.


Runs locally and privately in your browser!

Unlike similar products, it’s free to use and doesn’t store your data. All processing is done in your browser, and your files are never uploaded anywhere to fully respect user privacy. It runs well on computers and very slowly on smartphones; user beware.
