About Cognicull - Deep Dive Notes

Cognicull is a notebook for exploring questions and ideas that come up as you write. When something is unclear or you want to know more, create a linked Deep Dive Note. You can dive deeper from that note, too. At the top of the screen, each Deep Dive Note appears beneath the note it came from, with a line connecting them. ■ How it works 1. Write: Start with one note about something you want to research or think through. 2. Dive deeper: Use a Deep Dive Note to explore a question or learn more about a detail. 3. Keep digging: When something in that note catches your interest, create another Deep Dive Note. ■ What you gain • Keep the original note flowing. Put the details in a separate Deep Dive Note so the original reads as intended. • Take it one question at a time. Explore each question in its own note without having to research or understand everything at once. • See the path you took.…
