ANDREJ KARPATHY JUST KILLED THE $500/MONTH RAG SETUP - HIS OBSIDIAN SYSTEM DOES THE SAME THING FOR FREE

Karpathy built a knowledge base that handles thousands of documents, answers complex questions and finds connections across everything he’s ever read - no vector database, no embeddings, no complicated retrieval

just a clever markdown file structure that Claude Code navigates in 1-2 tool calls instead of 50 vector queries

raw folder catches everything - Web Clipper turns any webpage into markdown automatically, Claude Code conducts its own research and builds wikis on demand

master index keeps everything navigable - 3 wikis or 3,000 wikis, the path is always clear

2:52 he says the most important thing - most people don’t need real RAG

Obsidian covers 90% of use cases - $0 setup, $0 running costs, same output

LightRAG and similar systems only make sense above one million documents - 99% of people never get there

if you want to build your own Obsidian assistant in a few hours - full guide in the article below

even more than karpathy

mine too

do you use it often?

@noisyb0y1 love how he keeps it simple, makes me wanna rethink my whole setup

A new open-source tool called Graphify was built within 48 hours of Andrej Karpathy describing an LLM knowledge base workflow, enabling users to generate navigable knowledge graphs, Obsidian vaults, and wikis from any folder with 71.5x fewer tokens per query compared to reading raw files. It integrates with Claude Code and supports 13 programming languages, PDFs, images, and Markdown.
