For me it’s the Zettelkasten/smart notes app I’m working on. I’ve been a frustrated with how I take notes from books, videos, blog posts, etc. I want to build a zero-inbox style workflow around organising my notes consistently so that I can start to blog with a wealth of research and ideas at my fingertips. So I’ve started building Flowtelic.
Early (no signup/in browser storage) version is live at https://app.flowtelic.com.
A video showing how to use it is here: https://youtu.be/Zo9hIuffz_0
I’m documenting as I build this over on Twitter at https://twitter.com/Martin_Adams
