COG: A Self-Evolving Second Brain
tom_doerr · x · 2026-07-18
COG is a "self-evolving second brain" project built on AI agents + Obsidian + Git.
It replaces traditional databases with markdown files and uses version control for content syncing, aiming to let agents continuously iterate on notes, skills, and workflows. The project is designed to work with Markdown-reading tools like Claude Code, Cursor, Kiro, Gemini CLI, and OpenAI Codex, and includes Quick Start, Skills, Features, FAQ, and Setup documentation.
