On 3rd April 2026, Andrej Karpathy published a 1,500-word gist describing how to build a personal wiki using a folder of markdown and an LLM. Within 48 hours the X thread about it hit 16 million views . This skill packages Karpathy's idea — plus an AI-history organiser by Alex Freedman and the slash-command workflow shared by Greg Isenberg — into a single Claude Code skill that walks any user through the full setup. Built for non-technical readers of MarTech AI. --- Install The reliable way (works on every Mac, easy to update later): If /.claude/skills/ai-second-brain already exists, back it up first: Then open Claude Code in any folder and say: Set up my AI second brain. To update later: Verify it installed In Claude Code, type: You should see ai-second-brain in the list. If you don't, the folder is in the wrong place — re-run the clone command and double-check the destination path. --- What it does The skill walks you through three stages. You can do all three or pick one — just tell it. 1. AI Brain — exports your full ChatGPT and Claude history and turns the lot into a tagged, linked Obsidian vault you can search by topic, project, or person. 2. Karpathy Wiki — sets up a raw/ and wiki/ folder pair so Claude Code can compile a living wiki from your research.
