I didn't dig too deeply so maybe I missed it but your site doesn't mention how this works from a technical standpoint, i.e. do both reporters and devs need to have this extension installed, or just the reporters? If just the reporters, in what format are the bug reports captured? I.e. if it's a video plus metadata, does it save a .mp4 (or whatever) video file plus a .json file with the metadata?

Knowing more up front about how the whole thing works would make me more inclined to try it, especially since I'm wary of tools that take liberties with what they capture and store.
