I genuinely don't understand why everyone isn't using this yet. Andrej Karpathy (OpenAI co-founder) tossed out a deceptively simple take that exploded online: Quit using AI as a code typist. Use it as your memory amplifier. Aim Claude Code at a folder. Toss in anything articles, transcripts, PDFs, random notes. Claude reads, cross-references, and organizes it into a living wiki of what you’ve learned. It snowballs. Every new thing you add makes the whole system more useful. The setup: 1) Install Obsidian 2) Make a vault 3) Open that vault in Claude Code 4) Paste Karpathy’s “wiki” concept and tell Claude to implement it 5) Claude creates three pieces: - raw (incoming sources) - wiki (generated pages) - CLAUDE.md (the instructions that drive the workflow) 6) Drop any file into raw and say: ingest this 7) Query across your entire archive—anytime, indefinitely Five minutes of prep, and you’re done starting over from empty chats. Step-by-step walkthrough below.(CyrilXBT)
