Introduction

This is a Streamlit app for chatting with YouTube videos using Langchain, a Python library for building AI-powered chatbots that can answer questions based on documents. The app allows users to input a YouTube video URL, which is then transcribed and indexed to allow users to ask questions about the video. The app uses OpenAI for text embeddings and Langchain for question-answering with context.
