Hey HN, I'm one of the founders of Modfy.video - we just shipped Anno.so which lets you add timestamped comments and annotations (drawings, scribbles, notes) to videos & other media files.

We currently use it to add comments and markup to Loom videos about dev problems we share among our engineering team, it’s been a great help.

Anno.so supports uploaded videos, audio, YouTube videos, Loom videos, SoundCloud audio. It’s free to use with no sign-up required.

This is a project we spun out from a video editor we’re currently working on https://modfy.video if interested.
