What it is
STEM is a free web platform for bands and music collaborators to upload, mix and discuss song stems. Its multi-track mixer handles uploaded stems, while invited members can view or work on projects in real time. Timed comment threads can be attached to individual tracks or the master track. Share links use customizable permissions, allowing songs to remain private or become public. Users can render stems to MP3, save mix snapshots and export renders. Songs can be grouped into playable, shareable lists for albums, EPs, setlists or work sessions, and can carry lyrics, chord charts, reference tracks, session notes and other files. STEM is intended for discussion and shared decisions rather than music creation like a full DAW. Certain features require a Google account. The privacy policy says uploaded audio is accessible to the user and explicitly shared people. The Free plan costs nothing, with limited version history.
