I have recently been using tools like Athens research and LogSeq for connected note taking (see my previous post). A key thing you may want to check before choosing the one you will use is the lincese of each. As I write these lines Athens is friendlier if you plan to use it for work. LogSeq one, unfortunately, not so much. However if you plant to use it for fun, LogSeq is feature packed, the team keeps delivering and outstanding product, and the new publishing capability is great.
