Really cool! I'm building something with a little bit of overlap.
A personal data collection/archival platform with the goal of focusing on timestamping everything possible.
Basically, I realized that when I have multiple pieces of data (e.g. a note, some commands, a screenshot), almost always this data is naturally connected by time and that's also how I want to query it. So: it's nice to be able to e.g. create wiki links in note taking tools like obsidian but it would be nicer if one didn't even have to do the linking manually (most of the time).
I am building on postgres with a time series extension. On the client side I want there to be able to be multiple "collectors" that can collect data which is then sent to the server. So far I only have a keylogger collector but I have many more ideas such as a screenshot collector à la copilot etc.
I think the data you are recording would also be a candidate for a collector for this system.
