Karpathy's LLM Wiki turns local-first
This tutorial shows a practical, local-first implementation of Andrej Karpathy’s LLM Wiki idea: drop Markdown notes into a pipeline, use Ollama for on-device inference, LangChain for orchestration, and Obsidian as the living knowledge base. The result is a private wiki that extracts concepts, creates links between notes, and keeps growing as new material is added, making it useful for personal knowledge management, research, and long-running AI-assisted workflows.
// ANALYSIS
Hot take: this is less about “chatting with notes” and more about turning notes into a compounding system that can organize itself.
- –Strong fit for privacy-conscious users because the workflow stays local with Ollama instead of sending data to a hosted LLM.
- –Obsidian is a good target surface here because backlinking and markdown-native storage make the knowledge graph inspectable and portable.
- –LangChain is doing the boring but necessary glue work: ingestion, extraction, and linking logic.
- –Best suited for people who already maintain structured notes; it is more compelling as a workflow upgrade than as a beginner-friendly app.
- –The main risk is quality control: auto-generated links and concept extraction can drift without a review loop.
