It combines semantic vector search via pgvector with BM25 keyword search and reranking for high-accuracy retrieval. Every answer includes source attribution with document name and page number to prevent hallucinations. An interactive knowledge graph built with React Flow visualizes relationships between concepts across documents. The stack uses FastAPI, PostgreSQL with pgvector, OpenAI GPT models, React/TypeScript/Tailwind, and Docker on AWS EC2. Future plans include OCR support, RBAC, and multi-LLM options including local models like Llama 3. ## Full article daily.dev links to this article rather than hosting it.
