# RAG Agent with ChromaDB and Tavily

This repository contains a simple RAG agent that uses **ChromaDB** as a local vector store and **Tavily** for web search. The agent can decide whether to answer from the local knowledge base or fetch fresh information from the internet.

## Features
- Local semantic search with ChromaDB + Ollama embeddings (`nomic-embed-text`).
- Web search via Tavily API.
- Automatic source selection (local vs web) in responses.
- CLI chat interface.
