What is Wiki Graph?

Wiki Graph is an open-source command-line tool for managing long-text knowledge bases, built around Andrej Karpathy's LLM Wiki idea: compile knowledge into a maintained wiki instead of rereading raw material every time. It stores plain text in .wikg archives and generates searchable knowledge graphs that trace every claim back to its source. Text from PDFs, EPUBs, web pages, subtitles or recordings can be fed in after conversion.

Pros: what Wiki Graph does well

  • Turns long texts into a reusable knowledge base
  • Every graph entry links back to its source
  • Apache-2.0 licensed and works well with agents

Cons: where it falls short

  • Command line only and needs Node.js 22+
  • PDFs and other formats must be converted to text first

Who Wiki Graph is for

Researchers and builders who want AI to work from a compiled knowledge base.

Who can skip it
