YouChat Extension

Overview

YouChat is a Chrome extension designed to enhance your YouTube experience by processing video transcripts and generating insightful responses using Retrieval-Augmented Generation (RAG). This extension integrates with a backend server to fetch and analyze transcripts, providing users with context-aware answers and summaries directly within the YouTube interface.

Purpose

The primary goal of YouChat is to make YouTube content more interactive and informative. By leveraging advanced natural language processing, YouChat allows users to ask questions about video content and receive detailed, relevant responses based on the video's transcript. This is particularly useful for educational videos, tutorials, and long-form content where key information might be buried deep within the video.

Technologies Used

• LangChain: A framework for developing applications powered by language models. In YouChat, LangChain is used on the backend (see FAPI-Server) to process transcripts and generate responses using RAG.
• Rapid API YouTube Transcript API: This API is utilized to fetch transcripts from YouTube videos, which are then processed to provide context for user queries.
• Chrome Extension APIs: Used for creating the user interface and interacting with YouTube pages to display responses and capture user input.
