Full-Stack RAG Application — React Frontend & Python Backend with LLM

"AI is Good"

Production-grade RAG app: React UI, Python backend, vector search, and enterprise-ready LLM integration.

---

About

This repository contains a full-stack Retrieval-Augmented Generation (RAG) application built by HERE AND NOW AI. It pairs a modern React frontend with a robust Python backend to deliver an enterprise-grade document Q&A experience powered by large language models.

The application demonstrates best practices for building production-ready RAG systems: efficient document ingestion, vector storage, semantic retrieval, and streaming LLM responses — all wrapped in a clean, responsive UI.

Whether you are studying RAG architecture or building your own LLM-powered product, this codebase serves as a practical, deployable reference implementation.

Features

• React frontend with a responsive chat interface
• Python backend handling RAG pipeline (ingestion, retrieval, generation)
• Vector database integration for semantic search
• Streaming LLM responses for real-time UX
• render.yaml for one-click cloud deployment
• Enterprise proposal and demo guide included
