PDF Chat App

Welcome to the PDF Chat App! This web application allows you to chat with a chatbot powered by the OpenAI language model. It is designed to extract text from uploaded PDF files and answer your questions based on the content of the PDF.

This app is an LLM (Large Language Model)-powered chatbot built using the following technologies:

• Streamlit: A Python library that simplifies the process of creating web applications, ensuring a seamless and user-friendly experience.

• LangChain: LangChain provides the natural language processing capabilities that empower the chatbot to understand and generate human-like text.

• OpenAI LLM Model: The app harnesses the power of the OpenAI Large Language Model to provide accurate and context-aware responses in natural language.
