After Andrej Karpathy outlined the idea of “LLM Knowledge Bases” on April 3, 2026, developers built Graphify in under 48 hours. Graphify turns any folder of code, docs, and images into an interlinked markdown wiki you can query without vector databases or complex setup. It persists across sessions, builds backlinks and concept maps, and cuts future query costs.

• Karpathy's April 3, 2026 pitch for "LLM Knowledge Bases" proposed replacing RAG's fetch-at-query-time approach with an LLM-generated, persistent markdown wiki.
• Developers built Graphify from that idea in under 48 hours, and it racked up hundreds of GitHub stars within hours of posting.
• Graphify converts any folder (code, docs, images) into an interlinked markdown wiki—summaries, backlinks, concept maps, index—with one command, no vector database or retrieval pipeline needed.
• Because the wiki is plain markdown that compounds with each update, it's transparent, Git-versionable, and cuts future query costs compared to traditional embedding-based retrieval.
