They capture the interactions on the web page and "replay" them later in a deep analytic-esque session. The console is also available.

To me it looks like that the software is storing the whole document as state (including the mouse location) and uses some API to make the console available as well.

The stored data is in time-series format.

Later this stored data can be used to:-

Create frames for a video that can be played by the admin.
Play the document + interactions in browser itself (some how).
I was wondering if anyone is already aware of how this is possible?
