I built a similar tool in 2016 called Bugcam that does exactly this. It was also a chrome extension with the ability to tie console logs and network traffic to screenrecordings. Jam looks really polished and far more usable than the weekend hack I put together :) Well done!

The explanation for why OP built Jam was precisely the motivation I had for building Bugcam. I had transitioned to a team in Europe as part of an acquisition that had non-technical PMs filing bug reports. Their reports were completely nondescript and incredibly frustrating to decipher and repro.

I ended up abandoning the project due to other opportunities that came up. One interesting thing I noticed was that a significant percentage of users downloaded Bugcam to record themselves playing games for YouTube. Perhaps there was another opportunity there, but I decided not to pursue it.

Congrats on the product and best of luck Jam team!
