Right now, I have a mess of bookmarks, open tabs, and things saved haphazardly in different apps. I want a system where I can organize it all and also keep it reasonably private. Open to all suggestions, whether that’s an app or a tool or a personal trick or some completely different way of interacting with the internet.
You could use a bookmarks manager / read-it-later service where you’d save every article you read (or at least the ones you find most interesting). Most of them have a tagging system for organising by topic, some of them (including Readeck, the one I use) even locally save the article’s content so you can search in it too, not just in the titles.
