A vault that writes itself while you sleep.
One markdown source, one git clone. It runs across Claude Code, Codex, Gemini CLI, OpenCode, Antigravity, Hermes, and Pi - seven agents reading the same notes.
45 commands. Self-rewriting notes. A scheduled agent wakes up, breaks your inbox into atomic notes, wikilinks them into a graph, and generates topic pages overnight.
No vendor. No cloud sync. No vector database. No subscription.
Karpathy’s wiki is a knowledge base you maintain with an LLM. This one maintains itself.
It’s called obsidian-second-brain, by Eugeniu Ghelbur. Open source. Clone it tonight, read it in the morning.
