Developer Builds GraphRAG Dental Insurance Verifier With Persistent Session Memory

A developer created Cover-Clarity, a dental insurance claim verification tool, as part of the WeMakeDevs × Cognee Hackathon to help patients and doctors understand coverage decisions. The tool uses Cognee's GraphRAG technology to build a hybrid graph-vector knowledge store from Aetna Bronze Benefit Plan policy documents, enabling it to reason across complex cross-references rather than relying on simple keyword matching. Users can input a patient's medical history — including age, chronic conditions, medications, and allergies — and ask natural-language questions to receive precise, policy-traced answers. Cognee's session memory feature retains each user's conversation context for up to seven days, allowing follow-up questions without needing to re-enter patient information. The developer argues that standard retrieval-augmented generation would have fallen short because insurance policy documents contain layered, interlinked logic that flat vector search cannot navigate effectively.
