RAG Mutual Fund FAQ Chatbot

Designed and built a facts-only RAG chatbot (Gemini + ChromaDB) that answers live mutual fund queries — NAV, AUM, expense ratios — from a self-refreshing web-scraped knowledge base, with hard guardrails blocking investment advice and PII.

The system runs a scheduled scraper that refreshes the vector store nightly, ensuring answers are always grounded in current fund data. Guardrails were implemented at the prompt and output layers to prevent hallucination and regulatory risk.
