Kappa Graph is a semantic knowledge graph platform that ingests documents (PDFs, markdown, images, text), automatically extracts concepts and relationships, assigns confidence/grounding scores to claims, and preserves disagreements across sources. It provides multiple interfaces including a web visualization, CLI, MCP server for AI assistants, and a FUSE filesystem for semantic navigation.
This resource is most valuable when building research tools, documentation systems, or applications that need to find conceptual connections across large document collections and track source provenance. It's particularly useful when you need semantic search that goes beyond keyword matching, when building AI-powered applications that require grounded knowledge, or when creating audit-compliant systems that must trace claims back to original sources.
