What is a digital brain?
A digital brain is a folder of linked markdown notes that hold your standing context — your mission, goals, processes, people, and decisions. It starts from a single BRAIN.md file that links out to other notes with [[wikilinks]], forming a map your agents read before doing substantive work.
Why give your agents a brain?
Context is what makes an agent useful rather than generic. With a brain, every session already knows who you are, what you're building, and how you like to work — so you don't repeat yourself. As the agent learns something durable, it can file it back into the brain to compound over time.
The roadmap board
Your brain can include a roadmap — a board of what's planned, in progress, and shipped. Agents read it to know priorities and can move items as work progresses, keeping your plan and your work in sync. Granular renders the brain as a live, navigable map in the docs pane.
