Andrej Karpathy runs his brain on 1 plain text file while Boris Cherny built Claude Code around markdown and Obsidian is where the 2 collide. The man who coined vibe coding and the man who shipped the tool for it both picked the dumbest format on earth: plain .md files that cost $0. Here's what happens when you push it Obsidianmaxxing: Dump everything into 1 Obsidian vault, where 1 idea = 1 note books, code, strategies, half-thoughts, no folders, just links Open Claude Code inside the vault and every note becomes context it reads your brain like a codebase Stop asking it questions and start asking it to build tools for your brain One builder asked for a 3D map of his vault, and 1 evening later a force-graph engine was running on localhost:8766 every note a glowing node, every click pulling summaries, 3 outgoing links, 2 backlinks, the full layer. Then he asked for Terrain Mode. His vault now renders as a heatmap landscape with red peaks where he thinks the most and green flats where notes go to die 73% of his knowledge active and burning. He can see which parts of his own mind went cold. No plugin, no $30/month second brain SaaS just 2 prompts and a folder of text files. Karpathy trusts the format, Cherny built for it, and Claude turns it into an engine. Your notes were never the problem they never had an engineer.
