StemDeck, a free, open-source and local AI stem separator

StemDeck is a free, open-source tool that separates audio files into up to six individual stems (vocals, drums, bass, guitar, piano, and other) using local AI processing on your own machine. Users can import MP3, WAV, FLAC, OGG, MP4, or M4A files—or paste YouTube URLs—and then edit stems in a DAW-style mixer with features like muting, soloing, level balancing, and exporting, with no account, subscription, or cloud upload required. It positions itself as a free alternative to commercial cloud-based stem separators like Moises and LALAL.AI, prioritizing privacy and local processing.
