When I write I use Neovim as it's what I'm used to and the formats that I write in are non-WYSIWYG formats like Markdown or LaTeX. My partner is a non-technical person and an author who writes fiction books. She uses Scrivener for that. From what I can see it's a very high quality piece of software for that purpose.
I write songs, poetry, short stories, and of course all kinds of technical plans, and pretty much use google keep or VSCode(If I'm doing something associated with a got repo) for everything.<p>In theory I'd like to do more with actual paper, but it's just so much easier digitally.
