Shameless plug: I'm building Catch Notes (https://catchnotes.app/) for this

The idea is to capture notes/thoughts/todos quickly and send them to any service (Trello/Basecamp/Asana/etc...). For people doing deep work (programmers, designers, writers) you want to stay in flow but also be able to capture any random thought that pops in your head.

This project is a bit harder than ones I've done in the past because I'm trying to take it cross-platform (macOS first) and keep it native UI everywhere.

For the past few years I've been storing almost everything in Markdown and organizing files into yearly folders—I call it my "memex".

It ends up being pretty simple, but I end up missing some information that gets silo'd off in services like Trello.
