Organize your notes into a second brain
“My notes, links and ideas are scattered everywhere.”
AI can sort notes, link related ideas, summarize long files and answer questions from your own notes. Start with an inventory and approve changes folder by folder.
Fix it yourself in 3 steps
- Pick one notes app or folder as home base.
- Ask the AI for an inventory and a proposed structure before it moves anything.
- Approve folder by folder; then ask questions of your notes as you go.
Copy this prompt
Look at my notes in [folder/app]. First give me an inventory: topics, duplicates, and orphaned notes. Propose a simple folder and tag structure. Don't move, rename or delete anything until I approve each folder. Stop after the proposal.
Fill in the [brackets]. Each prompt says when the AI should stop, so it doesn't wander off.
