RAG-Bot (Retrieval-Augmented Generation)

Intelligent Document Q&A Assistant is an AI-powered chatbot that enables users to ask natural-language questions over their own documents and receive accurate, contextual answers using Retrieval-Augmented Generation (RAG) powered by Google Gemini.


Problem Statement

Across industries such as:

  • Legal
  • Finance
  • Healthcare
  • Construction
  • Research & Consulting

professionals deal with massive volumes of documents including: Contracts, Policy documents, Manuals, SOPs, Technical reports, and more.

Traditional keyword search and static FAQs fail to deliver:

  • Context-aware answers
  • Cross-document reasoning
  • Natural language understanding

As a result:

  • Employees spend hours searching PDFs
  • Critical insights are missed
  • Knowledge remains siloed

There is a strong need for an intelligent document-aware assistant capable of answering questions directly from enterprise knowledge bases.


Business Objective

To build a scalable, enterprise-grade RAG chatbot that enables:

  • 📄 Smart ingestion of large PDF and text documents
  • 🔍 Semantic retrieval using vector search
  • 💬 Natural language Q&A
  • 🧠 Context-aware reasoning using LLMs
  • ⚡ Instant answers from private knowledge sources

Proposed Solution

A full-stack Retrieval-Augmented Generation (RAG) system that:

  1. Accepts document uploads (PDF / text)
  2. Extracts and chunks text content
  3. Converts text into vector embeddings
  4. Stores embeddings in a vector database (FAISS)
  5. Retrieves relevant chunks based on user queries
  6. Uses Google Gemini 1.5 Flash to generate precise answers grounded in retrieved context

Key Features

  • Upload multiple PDF or text documents
  • Semantic document search using vector embeddings
  • Natural language chat interface
  • Context-aware answers grounded in documents
  • Fast retrieval with FAISS
  • Private document-level Q&A (no internet search)
  • Simple Streamlit UI
  • Cloud-deployed and scalable
