Chat with PDF using Llama3

Introduction

A simple Streamlit app interface that answers questions about an uploaded PDF document via Llama3.

This project implements a chat interface that allows users to ask questions about uploaded PDF documents. It leverages a Retrieval-Augmented Generation (RAG) approach, combining:

• Information Retrieval: Efficiently searching relevant passages in the PDF content using FAISS and text embeddings.
• Generative Language Model (LLM): Answering user questions in a comprehensive and informative way using Llama3, a large language model from Google AI for embeddings.

Features

• Upload multiple PDF documents.
• Ask questions about the content of the uploaded PDFs.
• Get answers generated by Llama3 based on the retrieved information.

• Python 3.x
• Streamlit
• PyPDF2
• langchain
• langchain_community
• langchain-groq (Groq API access)
• langchain-google-genai (Google Generative AI access)
• dotenv (for environment variables)

Legal Document Analysis

• Lawyers or legal professionals can upload contracts, agreements, or court documents and ask clarifying questions about terms, clauses, or procedures.
• The chat can highlight relevant sections, identify potential ambiguities, or offer preliminary interpretations based on the document's content.

Technical Documentation Exploration

• Software developers, system administrators, or technical support personnel can upload user manuals, technical specifications, or troubleshooting guides.
• The chat can answer questions about specific features, configuration options, or troubleshooting steps based on the information within the documents.

Customer Service Chatbots

• Companies can leverage this technology to build chatbots that answer customer questions about product manuals, FAQs, or service policies.
• Users can upload relevant documents and get immediate, context-aware responses based on the retrieved information.

Educational Materials and Assistive Technologies
