Built for

Musicians & Producers

Share rough mixes with bandmates. Mark the verse that needs reworking. Flag the snare that's too hot. All without leaving the track.

Teachers & Students

Leave feedback on student performances. Students can review notes at each timestamp and understand exactly what to practice.

Podcasters & Editors

Mark edit points, flag audio issues, and leave production notes. Your editor sees everything in context, synced to the timeline.
