How do you manage, utilize knowledge with AI?

Every day I (and I assume most of us, devs, creatives…) read a bunch of articles, papers, code snippets, AI responses, newsletters... By the end of the day, some of that feels worth saving in some kind of system.

I’ve been testing out AI knowledge management apps like notion, saner, mem… but I’m still figuring out what actually works long-term.

Curious what others do. How do you store and organize things you come across and make use of them when needed?
