I genuinely don't understand why everyone isn't using this yet. Andrej Karpathy, a co-founder of OpenAI, posted a simple idea that hit 16 million views: stop using AI to write code, use it to build a second brain. You point Claude or Kimi at a folder, drop in any source — an article, a transcript, a PDF — and it reads it, links it, and files it into a living wiki of everything you know. It compounds like interest. the more you feed it, the smarter it gets. here's the whole thing: > install Obsidian, create a vault, open it in Claude Code > paste Karpathy's wiki idea and tell it to build the system > it makes three folders: raw for sources, wiki for its pages, a CLAUDE.md that runs it > drop any source into raw and say "ingest this" > ask questions across everything you've ever added, forever Claude for deep reasoning. Kimi for reading dozens of files at once with 256K context at a fraction of the cost. five minutes to set up, and you never start from a blank chat again. full step-by-step A–Z guide below.
