LineageLens

LineageLens is a web app (with optional desktop agent) for teams building knowledge graphs who keep getting burned by stale, untraceable facts. It automatically captures provenance for nodes and edges—where a claim came from, which pipeline produced it, what model/prompt transformed it, and when it was last validated. It plugs into common graph stores and ETL/ELT jobs, then provides a “why is this true?” view for any entity: source documents, extraction spans, confidence, transformations, and downstream dependencies. When a source changes, LineageLens flags impacted triples and generates a review queue so humans can re-approve or roll back. This is not a full graph platform; it’s a governance layer focused on lineage, auditability, and change impact—areas most teams hack together poorly. Expect a pragmatic UI, strong APIs, and exportable audit reports for compliance.
