Based on the comments (I'm also unfamiliar with emacs), you may also want to look into Obsidian. It keeps a local vault of files with some file structure magic to basically let you both easily jot down notes for later and find them (tag/header searching, etc) but also link them together (select some text -> extract into new note, and it backlinks, etc). For a bit I tried to get into being a "power user" of it, using scripts to collect things, add interactive widgets, bla bla. But at the end of the day, I've found it much more enjoyable to use in a very general way, linking documents together (I keep a personal writing vault, and a separate work vault) and giving myself ways to mash through ideas when typing makes more sense.
