Quark: A simple note-taking system (lorbic.com)

I like these symbols as ways to contextualize info in files, similar to the bullet method

Searchable notes and notes that can be selectively shared as text with LLMs have been my top uses lately.

I think the thing I'd struggle with if I went Quark-only is dealing with indentation as I work with notes.

I've been using a very similar convention for years (roughly a subset of markdown), never thought of giving it a name. My convention benefits from out-of-the-box syntax highlight, though.

I swear I've seen this before, or something very similar. Love the simplicity.

Is this a spec or software? Where can I run or use it?
