TL;DW adds quick summaries to YouTube thumbnails. Load the Chrome extension to get started.

1. Open chrome://extensions in Chrome and enable Developer mode.
2. Click Load unpacked and select the extension/ folder inside this project.
3. For a hosted backend, open the extension's Options and enter this site's address and your TL;DW access token.
4. Open or refresh YouTube, hover a video thumbnail, and click TL;DW.

Your Gemini API key stays on the server. The extension uses a separate TL;DW access token.
