Not exactly the same but I'd also point to Paul Kinlan's FolioLM as a very interesting project in this space. A very nice browser extension,

I've been trying to arrive to something like this with my own sidepanel extension called Klue but its more of a user notes + web page context approach. Nice to see another take on this! https://chromewebstore.google.com/detail/cackjmmgcmnkjnffabk...
Thanks for sharing! We need more projects like this in the JS ecosystem.
