I've been thinking about how we capture and organize ideas - the stuff that pops into your head when you're walking or making coffee, and especially the connections you make between projects from totally different domains. Most note-taking apps force you to decide upfront how to organize things, but that's not how thinking actually works.

Core Philosophy

The Deep Notes app implements a two-stage knowledge processing workflow: raw ideas are captured quickly in an 'inbox' without worrying about structure, then gradually promoted to structured notes with proper titles, concepts, and relationships. This mirrors how our minds naturally work - we have fleeting thoughts that need time to develop into coherent insights.
I re-discovered the "Deep Notes" practice via the book ***Writing is not Magic, it's Design .*** Here, instead of index cards, you dump everything into an inbox first, then gradually promote the good stuff into structured notes with concepts and links. It's like how you might sketch something rough first, then clean it up later when you understand what you're actually trying to say.

Connection to Broader Work
This is definitely part of a broader pattern in my work around organizing information and making connections visible. You can see similar thinking in my FileGraph project (tag-based file management) and my Framework for Organizing Iterative Workflows writing. I keep coming back to this idea that the most interesting stuff happens at the intersections - like how this notes app uses both programming and organizational systems thinking.
The app is very much inspired by Doug Engelbart's vision of computers as tools for augmenting human intelligence, rather than just doing computational tasks.
