Two shared brains
Two Obsidian vaults of plain notes: a private one for my life and work, and one I share with my co-founder. Every AI tool I use reads them first, so I never re-explain my context.
- Why
- I was re-explaining the same context to every AI tool, every session. Now they all start from the same notes.
- How long
- Since spring 2026, split in two in July 2026
How I built it
- Kept my notes as plain text files in Obsidian, sorted into projects, areas and an archive.
- Gave every AI tool one instruction: read these notes first, and write new decisions back.
- Split them in two in July: everything for our company moved to a vault I share with Frances, and my personal notes stayed private.
- The shared one is backed up on GitHub, so both of us and every AI read the same version.
- To copy it you need
- Obsidian (free), Claude, or the AI of your choice, and a few minutes of setup.

I want to copy a setup from Carley Hart's desktop on whatarewebuilding.ai/desktops/carley: a folder of plain notes that every AI tool reads first, so you never re-explain your context. She keeps one private vault and one shared with her co-founder, and every AI writes new decisions back into it. Help me start one: ask me about my work and projects, then write my first five notes and the one instruction I should give every AI tool so it reads them first. Ask me for anything you need.
