@independentpen@aspiringcat@academicchatter They are all excellent and serve different purposes. @zettlr is the best one if you're only interested in academic work. If you prefer to work with an outliner or journal-style notes, @logseq is the best one. They are both open-source. @obsidian is better if you're interested in a more flexible and interlinked note-taking system. This is the one I use. All three apps use local markdown files to keep your notes. Hope that was helpful :ablobsmile:
