Karpathy's LLM Wiki 'Second Brain' Pattern Goes Mainstream — 100-Article Research Wiki Built Without Writing Code, Apify Ships Automation Tool
Andrej Karpathy published an LLM Wiki GitHub Gist that proposes replacing RAG with a persistent, LLM-maintained markdown wiki that compounds over time. His personal research wiki has grown to ~100 articles and 400,000 words, built entirely by AI without Karpathy typing code since December. The pattern has spawned ecosystem tools including Apify's 'Second Brain Builder' automation, and multiple Medium/Substack analyses calling it the future of personal knowledge management.
