Karpathy published a viral gist (April 2026) describing the LLM Wiki Pattern — using LLMs to build and maintain personal knowledge bases as structured markdown files. The idea gained massive traction on X, with many people implementing it using Claude Code and Obsidian.
Key details from the gist:
- Uses ~100 articles / ~500K words in his own wiki
- Relies on index files rather than embedding-based retrieval
- Left the idea intentionally vague for customization
- Considers it related to Vannevar Bush’s Memex (1945)
