YouTube-Transcript-Summarizer---Streamlit-App

A Streamlit-based web application that extracts and summarizes the transcript of a YouTube video using Google Generative AI (Gemini) API.

Purpose

This tool helps users quickly understand the contents of a YouTube video without watching the entire content. It is ideal for researchers, students, content creators, and busy professionals who want quick insights from educational or lengthy videos.

How It Works

1. User pastes a YouTube video link into the app.
2. The transcript is automatically fetched using the YouTube Transcript API.
3. The transcript is then passed to Google's Gemini (Generative AI) API.
4. Gemini generates a concise and informative summary (within 250 words).
5. The summary is displayed on the page alongside the video thumbnail.
