The problem
Everyone says 'get it out of your head and into a system,' but nobody sits you down, asks the right questions, and does the filing for you.
What Claude Code did
Claude built Amy as a tool-using agent: members step into the circle with an invite code, and Amy converses, asks, and files. Each member gets their own folder of markdown files that Amy creates and updates as she learns more, so the Second Brain is readable by humans, portable, and never locked in a proprietary format.
The result
Members talk, Amy files, and a real knowledge base accumulates per person. The markdown-folder architecture means a member's Second Brain is theirs: openable in any editor, forever.
