YouTube Gemini Summarizer

Quickly understand the content of YouTube videos by generating concise summaries using Google's powerful Gemini AI models, right on the video page!

This script adds a convenient panel to YouTube video pages, allowing you to:

  • Generate AI-Powered Summaries: Get the gist of a video without watching the whole thing.
  • Use Your Own Gemini API Key: Securely input and save your Google Gemini API key.
  • Select Your Preferred Model: Automatically fetches compatible Gemini models (like gemini-pro, gemini-1.0-pro, gemini-1.5-flash, etc.) and lets you choose one.
  • Choose Summary Language: Select from a wide range of languages for your summary.
  • Right-to-Left (RTL) Support: Correctly displays summaries in RTL languages like Hebrew, Arabic, and Yiddish.
  • View Summaries Directly: The generated summary appears in a dedicated text area within the panel.
  • Automatic Transcript Retrieval: The script intelligently tries to extract the video's transcript or closed captions.
  • User-Friendly Interface:
    • A discreet "Summarize" button appears on mouse-over of the video player.
    • The settings panel can be easily toggled.
    • Your preferences (API key, model, language, panel visibility) are saved.
  • Status Notifications: Get real-time feedback on the summarization process.

How to Use:

  1. Get a Gemini API Key:
    • You'll need a Gemini API key from Google AI Studio. You can get one here.
  2. Install the Script:
    • Make sure you have a userscript manager like Tampermonkey, Greasemonkey, or Violentmonkey installed in your browser.
    • Install this script.
  3. Open a YouTube Video:
    • Navigate to any YouTube video page (youtube.com/watch*).
  4. Access the Summarizer Panel:
    • Hover your mouse over the video player. A "Summarize" button will appear in the bottom-left area of the player.
    • Click this button to open (or close) the summarizer panel.
  5. First-Time Setup:
    • In the panel, enter your Gemini API Key into the "Gemini API Key" field.
    • Click the "Save & Fetch Models" button. This will save your key and load the available Gemini models into the dropdown.
    • Select a model from the "Select Model" dropdown.
    • Choose your desired "Select Summary Language".
  6. Summarize!
    • Click the "Summarize Video" button.
    • The script will fetch the transcript and send it to the Gemini API. The summary will appear in the text area below.

Important Notes:

  • The accuracy and availability of summaries depend on the video having a transcript or captions and the capabilities of the selected Gemini model.
  • The script attempts to interact with YouTube's UI to open the transcript panel. YouTube updates its site frequently, which might occasionally affect this part of the script. A fallback method to get caption data is included.
  • Ensure your Gemini API key is correctly configured and has the necessary permissions.
  • This script makes requests to generativelanguage.googleapis.com.

Enjoy a more efficient YouTube experience!
