Free AI-powered YouTube video summaries. Pin the extension and click the Nutshell icon while watching a video to get started.
Nutshell Video extracts YouTube transcripts and generates AI summaries in seconds. One click on the floating button, instant results in a clean sidebar. Three summary levels:
Overview — Quick 1-2 paragraph recap
Standard — Key points and takeaways
Detailed — Section-by-section analysis
How it works: Press ALT+N (Windows) / OPTION+N (Mac) or click the Nutshell button on any YouTube video with captions. The extension pulls the transcript automatically and sends it to Claude AI. Summaries stream in real-time - no waiting for completion.
We recommend pinning the extension for quick access.
Built for reliability: Smart transcript extraction with multiple fallback methods. Handles both automatic and creator provided transcripts.
Clear error messages when videos genuinely lack captions. What we don't do:
* No account required
* No API keys to configure
* No tracking or analytics on your viewing
* No extension access to anything outside your current YouTube tab
