MultiPDF Chat App

You can find the tutorial for this project on YouTube.

Introduction

The MultiPDF Chat App is a Python application that allows users to chat with multiple PDF documents. Ask questions about the PDFs using natural language, and the application will provide relevant responses based on the content of the documents. The app now integrates with Azure OpenAI, leveraging its capabilities to generate accurate answers to your queries. Please note that the app will only respond to questions related to the loaded PDFs.

How It Works

The application follows these steps to provide responses to your questions:

PDF Loading: The app reads multiple PDF documents and extracts their text content.
Text Chunking: The extracted text is divided into smaller chunks for more effective processing.
Language Model Integration: Through Azure OpenAI, the application generates vector representations (embeddings) of the text chunks.
Similarity Matching: When you pose a question, the app compares it with the text chunks to find the most semantically similar ones.
Response Generation: The identified chunks are then processed by the Azure OpenAI model, which crafts a response based on the relevant PDF content.

Dependencies and Installation

To install the MultiPDF Chat App, follow these steps:

Clone the repository to your local machine.
Install the necessary dependencies:
```
pip install -r requirements.txt
```
Set up the OpenAI integration with Azure by filling in the required fields in the .env file:

OPENAI_API_KEY=your_openai_api_key
OPENAI_API_TYPE=azure
OPENAI_API_VERSION=your_openai_version
OPENAI_API_BASE=your_openai_base_url

Usage

To get started with the MultiPDF Chat App:

Ensure all dependencies are installed and the OpenAI details are set in the .env file.
Launch the app using the Streamlit CLI:
```
streamlit run app.py
```
Your default web browser will open to display the app interface.
Upload multiple PDF documents as directed.
Use the chat interface to pose questions related to the uploaded PDFs.
