## Overview

This is a browser-based GenAI chat application. A user enters a message in the React chat interface, which posts it to the FastAPI endpoint; the endpoint sends it to Hugging Face’s FLAN-T5 inference API and returns a reply for display. The sampled source supports this request-and-response path. No README or additional product capabilities were provided, so the graph reflects only the evidenced workflow.

Main entry points: [`backend/main.py`](https://github.com/wafiur06/genai-chatbot/blob/main/backend/main.py) (Chat endpoint), [`frontend/src/App.jsx`](https://github.com/wafiur06/genai-chatbot/blob/main/frontend/src/App.jsx) (Chat interface), [`frontend/src/main.jsx`](https://github.com/wafiur06/genai-chatbot/blob/main/frontend/src/main.jsx) (React entry)
