I think it's time for people to build a local database of every site they've ever visited, and then they can give their LLMs access to that. I might be willing to pass this data off to a company to store for me. Companies already store all my emails and money--why not trust them with this too?

Like, all the comments of this post would go into my personal database simply because I loaded the page, and it would help me find old information I've read, and could also inform LLMs I use.

This should be built into browsers.
