KGDocLink
KGDocLink is a web app (with optional desktop connector) that builds and maintains a lightweight knowledge graph from the documents teams already have: Google Drive, Confluence, Notion, SharePoint, and internal wikis. It ingests pages and PDFs, extracts entities/relationships, and links them to source passages so users can verify and fix mistakes instead of trusting a black box. The product focuses on “good-enough” graphs for real workflows: onboarding, incident retros, architecture decisions, policy compliance, and customer escalations. Users can search the graph, ask questions with citations, and export to Neo4j/RDF when they outgrow the built-in store. It also tracks drift: when a doc changes, it flags impacted nodes and relationships for review. This is not a research-grade ontology tool; it’s a pragmatic graph layer that teams can actually keep current.
