Worth mentioning here that LogSeq can work with markdown or org-mode files. In my personal setup one of my LogSeq nodes points to my BrainTool.org file which holds all my bookmarks, web-resource pointers and associated notes. This way I can bounce between working in Chrome, emacs and LogSeq all referencing the same underlying data model. (With Orgzly for a read-only view on my phone.)
