Doesn't work for me. The language selector seems to change on its own, the right pane never finishes "Loading...", the feedback button opens a blank page.

Also, the start page shows that the right pane is for the camera view of the participants. Why would I want to see the interviewee's face? I want to know how they think, not how they look.

A better use of that space would be a drawing tool, as sometimes it's easier to explain something by making a diagram. Build that and I'll use it.
