It's similar but allows users to give control to remote users for a specific site (I believe, haven't tested yet). It also has annotation functionality like doodles.
@nbashaw we had a recording feature on live DOM elements. Since the recordings can be shared via a link, it's helpful for website QA, etc. Super helpful for inspecting the DOM as you see issues happening. (didn't see this until we've already shut down, thanks for trying it out!)
