There are hundreds of these note taking programs now, and they all suck. Maybe they're fine if you don't really know how to use a computer, but if you're a developer or some other kind of hacker, and you use a text editor, like Vim/Neovim, Emacs, VS Code, or something else, your notetaking system should be in your text editor. These flashy new note taking programs basically just stick a crappy WYSIWYG text editor inside a web browser (Electron, yuck) and add a few opinionated components like tags or encryption, then try to charge you $9/mo for that, in perpetuity. But you've had the power within you this whole time: encryption with gpg, sync with git, search with grep, editing with your $EDITOR. If you need more, there are some editor plugins that supercharge note taking: vimwiki and vim-notes for vim; org-mode and org-roam for Emacs; Foam for VS Code, and so on. No need to reinvent the wheel.
