Personal Codebase Knowledge Graph Builder
PKGB (Personal Knowledge Graph Builder) is a local-first, free-tech system that transforms repositories, documentation, notebooks, PDFs, and CLI history into a queryable knowledge graph. It combines a semantic vector index for similarity-based retrieval with a property graph for structural exploration — all with full provenance tracking (file path, line ranges, timestamps). No cloud services are required; every component runs offline on the local machine.
