Features

Everything the modern ear needs to review a mix.

Share, review, and refine -- keeping every note and revision in one place, without losing track of which version someone heard.

Timestamped feedback, pinned to the waveform.

Click any moment to drop a comment. Drag across a region to scope a note to a phrase. Tag instruments, mention collaborators, or reference shared glossary terms so "more air" never gets misread again.

SM 01:14Vocals feel buried. Boost mids around 2-3 kHz?
JK 02:08Kick/bass clash -- sidechain the low end.
RP 03:02Love the breakdown. Ship it.

Team access, right-sized.

Invite admins and clients with separate roles and separate tokens. Share a link, control who can listen, comment, or upload. Mentions route notifications to the right person.
