About this extension
No time to watch a 40-minute video? One click is all it takes.

Connect YouTube directly with Google Gemini.

How it works:
1. Open any YouTube video
2. Click the Extension toolbar icon (only active on YouTube video pages)
3. A new Gemini tab opens automatically
4. The prompt is typed and submitted for you
5. Read your summary in seconds

If automatic input fails, the prompt is copied to your clipboard with a notification — just paste it into
Gemini (Ctrl+V).

No login, no servers, no data collection.
Requires a Google account for gemini.google.com.
