What STEM is
STEM is a web platform for bands and music collaborators to upload, mix, and discuss song stems. Its multi-track mixer console lets users work with uploaded stems, and invited band members can view or collaborate on projects in real time. Timed comment threads attach discussion to an individual track or the master track, helping collaborators focus feedback on particular parts of a song. Share links have customizable permissions, so users can keep songs private or share them publicly.
Users can render stems into an MP3, save mix snapshots, and export a render. Songs can be organized into playable, shareable lists for albums, EPs, setlists, or work sessions, and can include lyrics, chord charts, reference tracks, session notes, and other supporting files. STEM is meant for discussing music and making decisions together, rather than creating music like a full DAW. Some features require signing in with a Google account. The free plan costs nothing, and version history is limited. The privacy policy says uploaded audio is accessible to the user and people they explicitly share it with, and that personal data is not sold or shared with third parties.
