I haven’t seen anyone mention Readeck. I use Readeck for those ‘read it later’ articles, etc. It has a Firefox extension. I’ve found it works very well. You can highlight a paragraph of an article, and save that to Readeck as well. In fact, when I consult with AI, I’ll highlight the entire page and shoot it to my Readeck instance, otherwise it will just link the AI platform and not the content.
