Drop your stems. Click anywhere on the waveform. Leave feedback pinned to the exact moment — and watch your collaborators reply in real time.
A quick look at dropping a stem and leaving feedback right on the waveform.
Click anywhere on the waveform and drop a note pinned to that millisecond. No more “around the 2-minute mark” — your collaborators land on the exact moment you mean.
See who's listening, watch notes appear live, and reply as the ideas land. STEMR keeps the whole session in sync — like you're all at the same desk.
Up to 2GB per stem, streamed straight to the cloud — no waiting, no compression, no “can you re-send that WAV.” Your full-quality files, ready to play in seconds.
Group stems into projects and revisions so the latest bounce is always obvious. Feedback stays attached to the take it was about — nothing gets lost between v3 and v4.
Upload a mix, a bounce, or the full stem set. It's playable the moment it lands.
Leave a timestamped note exactly where the moment happens.
Collaborators reply in real time until the track is done.
Start a project, drop your first stem, and invite the people whose ears you trust.
