User builds personalized AI "second brain" with Claude, Codex, and Obsidian

A user has developed a personalized AI system that functions as a "second brain" by integrating multiple AI models and tools. This system, built on an Obsidian vault of markdown notes, allows for voice-based queries and automated note-taking from lectures and videos. The setup utilizes Claude and Codex for shared memory and task execution, with a router directing queries to specialized search indexes like ChromaDB and LightRAG for efficient information retrieval.
