Enterprise RAG Chatbot System

Production-ready RAG chatbot for internal knowledge base and customer support

Back to Portfolio

Project Overview

The Enterprise RAG Chatbot System is a sophisticated AI-powered conversational platform designed for both internal knowledge management and customer support. Built using cutting-edge Retrieval-Augmented Generation (RAG) technology, the system combines the power of LangChain, OpenAI GPT-4, and vector databases to deliver accurate, context-aware responses with source attribution. This production-grade solution enables organizations to leverage their existing knowledge base while providing instant, intelligent responses to user queries.

Live Demo Coming Soon

Interactive demonstration of the Enterprise RAG Chatbot will be available here

Key Features

RAG Architecture

Advanced Retrieval-Augmented Generation combining semantic search with GPT-4 for accurate, contextual responses.

Knowledge Base Integration

Seamlessly integrates with internal documentation, wikis, PDFs, and databases to create a unified knowledge source.

Source Attribution

Every response includes citations and links to source documents, ensuring transparency and verifiability.

Context-Aware Conversations

Maintains conversation history and context for natural, multi-turn dialogues with users.

Multi-User Support

Handles concurrent users with session management and personalized conversation tracking.

Real-time Responses

Fast response times with optimized vector search and efficient LLM integration.

Technology Stack

LangChain OpenAI GPT-4 ChromaDB FAISS Python FastAPI REST API

System Architecture

RAG Pipeline

  1. Document Ingestion: Load documents from various sources (PDFs, docs, web pages)
  2. Text Chunking: Split documents into optimal-sized chunks for processing
  3. Embedding Generation: Convert text chunks to vector embeddings using OpenAI
  4. Vector Storage: Store embeddings in ChromaDB/FAISS for fast retrieval
  5. Query Processing: User query is converted to embedding
  6. Semantic Search: Find most relevant chunks using vector similarity
  7. Context Assembly: Combine retrieved chunks with conversation history
  8. LLM Generation: GPT-4 generates response using retrieved context
  9. Source Attribution: Include references to source documents in response
