It is becoming f*cking dangerous: thanks to this exact setup, I automated my work and generated $16,400 two months back
Andrej Karpathy, co-founder of OpenAI, sparked 24 million views with one idea: stop using AI for code, use it to build a second brain
Point Claude Code at a folder, drop in any PDF, transcript, or article, and it builds a living wiki that grows smarter the more you feed it
Quick setup:
1. Create an Obsidian vault and open it in Claude Code
2. Paste Karpathy's wiki prompt and let Claude build it
3. Claude creates three folders: raw (sources), wiki (pages) and CLAUDE.md (config)
4. Drop sources into raw and say "ingest this"
5. Query your entire knowledge base forever
Set it up in 5 minutes and never start from a blank chat again
