Andrej Karpathy, a founding member of OpenAI, coined the term vibe coding. It means describing what a program should do and letting AI write much of the code. His wiki project goes a step earlier, to what he calls the idea file. From there, AI turns articles, research papers and notes into a knowledge base that keeps itself up to date.
He describes the idea file as something a person can copy into an AI system that follows instructions and carries out tasks. The AI then helps build the system from it. That changes what counts as the asset. In the old model, code was the asset because it made the system work. In his model, the idea file comes first, because AI can turn clear instructions into working systems.
The setup has three parts. Raw sources sit in one folder and wiki pages in another, while a rule file tells the AI how to maintain the whole system. When a new source is added, the AI reads it, pulls out the useful points, updates related pages, links connected ideas and flags contradictions. The person supplies sources, judgement and direction instead of writing every page by hand.
Karpathy describes the setup in software terms. Obsidian, a note app for linked knowledge, is the coding workspace, the AI model is the code writer and the wiki is the code.
Companies create the raw material for such a wiki every day, through research, customer calls, meetings, product work and internal decisions. Much of it loses value because it is scattered across documents, chats, slide decks and personal notes. People repeat the same searches, and teams rebuild the same context. Useful knowledge exists, but it is not organised in a way AI can keep using.
Karpathy’s model gives that material a cleaner structure, because the AI reads new material once instead of rediscovering information every time someone asks a question. A company with clearer instructions, cleaner sources and stronger habits for keeping knowledge gives AI better material to start from. That lowers the cost of repeated knowledge work and makes a company less dependent on whoever remembers where something was written.
