As a former user of a number of proprietary, web-based notetaking app services, I come from the future to tell you never to sign up for one of these. Not even if it's free. The company will fold after a year or two, and sometimes take your notes down with it. You'll be left with the nightmare of losing all your notes—or, in the best-case scenario—at least having to convert all your notes to a new format. You need: (1) free and open-source software, which (2) uses open and future-proof file formats. I use org-mode and org-roam on Emacs, but there are plenty of other solutions for those outside the Emacs world. Others in this thread recommend Foam for VSCode, and Obsidian for a standalone solution.
