Yeah I used the “message to self” approach for a while too — it works surprisingly well 🙂
What I ended up building is basically a very minimal “capture layer”, where no matter the context (share, paste, shortcut, etc.), everything goes into the same place instantly, without deciding upfront what it is or where it belongs.
It’s not really a note-taking tool — more like a universal entry point.
