LLM Second Brain: Obsidian + AI Wiki Compiler

Build a personal LLM-powered knowledge base where you collect raw sources, an LLM compiles them into a structured wiki, and Obsidian serves as your read-only IDE. You never edit the wiki manually — the LLM writes everything.

Based on Andrej Karpathy's LLM Knowledge Bases setup (April 2026).
