YouTube Summarizer (Gemini)

About

Save time. Watch smarter.

YouTube Summarizer uses Google's Gemini AI to generate instant, intelligent summaries of any YouTube video — so you can get the information you need without sitting through hours of content.

How it works:
Paste any YouTube URL, choose your preferred summary style, and hit Summarize. Your summary appears in seconds, powered by the Gemini API using your own API key.

Four summary styles to fit every use case:

Short TL;DR — A quick overview for when you're in a hurry
Bullets + Timestamps — Key points linked to moments in the video, great for navigation
Chapterized Summary — Content broken down by topic/chapter for structured viewing
Study Notes — Key takeaways plus quiz questions, perfect for learning and revision
Built with privacy in mind:
Your Gemini API key is stored locally in your browser — never sent to any third-party server. The extension only communicates with Google's Gemini API and YouTube directly.

Who is this for?

Students who want to quickly review lecture recordings or educational content
Professionals researching topics without time to watch full videos
Anyone who wants to decide if a video is worth watching before committing
Requirements:
A free Google Gemini API key (available at Google AI Studio). Setup takes less than a minute.
