Currently I'm using org-mode in Emacs for note-taking, journaling, habit-tracking, task management, any many other things. I've heard good things about Notion and Obsidian but haven't made the switch because I like the flexibility of Emacs. I learned about Anytype a few months ago and it looked like it might be a good replacement. I'd been holding out because back then it didn't have local-only mode. In their latest release, they added local-only mode so maybe it's finally time to try it. First though, I have to figure out if it works on NixOS.
