Public Health Graph RAG WhatsApp Assistant
Course knowledge becomes a conversational Graph RAG assistant on WhatsApp.
OutcomeGraph-backed public-health learning answers over WhatsApp
15 days · 2-person team
The Challenge
Public-health course content needed to be queryable through a conversational channel. Simple search was not enough because topics, concepts, and dependencies required relationship-aware retrieval.
What We Built
We partnered with HCL Foundation · Public health learning to ship a production-ready AI platform for Public Health · E-Learning. We built a content ingestion pipeline that structures learning content into a Neo4j knowledge graph. We combined graph retrieval with Pinecone vector search and OpenAI RAG for richer answering. We kept the engagement as a focused POC/build that proves Graph RAG delivery for public-health learning content.
