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.
