Ytsum: Summarize YouTube Videos

No subscription needed. Use your Anthropic API key & Claude 3.5 Sonnet to summarize YouTube videos. Feedback welcome 🙏 [email protected] Instructions: - Click the extension icon and enter your Anthropic API key (which you can get here: https://www.anthropic.com/api) - Open a YouTube video, scroll down a little, the extension box should appear above the comments section - Click fetch transcript (if auto fetch is enabled you can skip this step) - Click analyze transcript (this does not happen automatically) Note: - Token counter is slightly off (in general the estimate is higher than the actual usage) - Fails sometimes, if the response from the API isn't perfectly formed - Does not work with extremely long videos due to token limits Changelog: 1.05 update model to claude sonnet 4.5
