In its own words

Abouteugeniughelbur/obsidian-second-brain

Stop re-explaining your projects, decisions and people every session. 45 commands: hybrid semantic search, self-rewriting notes, key-less web research, and scheduled agents that maintain the vault while you sleep.

README.md

One codebase. Seven CLIs. Same brain.

Your vault outlives whichever CLI you switch to.

obsidian-second-brain: an AI second brain for Obsidian that Claude can actually search

An evolution of Karpathy's LLM Wiki pattern : a vault that rewrites itself.

Every source updates existing pages instead of just appending new ones. Contradictions reconcile automatically. Your vault compounds while you sleep.

Powered by OKM - Open Knowledge Metabolism : every stored fact is timeless, dated, or a pointer - so your knowledge base never fills with facts that used to be true.

Built for developers founders and operators writers researchers - pick a preset at setup

Start with three: /obsidian-init to set up, /obsidian-save to capture, /obsidian-find to recall. The other 42 are there when you need them.
