YouTube Summarizer with Gemini
A Firefox extension that instantly summarizes YouTube videos using Google's Gemini AI.
The Problem
YouTube is full of content with clickbait titles and thumbnails that can really suck you in. AI is great at summarizing videos, but it's really inconvenient to have to copy the video link, open a new tab, and paste it into an AI tool just to get a summary. What's the best way to get these summaries without leaving YouTube?
The Solution
I built the YouTube Summarizer with Gemini - a Firefox extension that allows you to quickly summarize YouTube videos in the Firefox sidebar without leaving the page.
Key Features
- 🚀 One-Click Summarization: Click the extension icon on any YouTube video page to instantly open Gemini with a pre-filled summarization prompt
- 🖱️ Right-Click Context Menu: Right-click on video thumbnails anywhere on YouTube to summarize videos without navigating to them
- 📱 Sidebar Integration: Opens Gemini in a convenient sidebar panel for seamless multitasking
- ✅ Auto-Mark as Watched: Automatically marks summarized videos as "Already Watched" to keep your YouTube feed clean
- ⚙️ Customizable Settings: Configure prompt templates and toggle features through the options page
How to Use
- Install the extension from the Firefox Add-ons Store
- Navigate to any YouTube video page or page with video thumbnails
- Summarize using either:
- Click the extension icon in the address bar (on video pages)
- Right-click any video thumbnail and select "Summarize with Gemini"
Try It Out
