What YouTube Summary with ChatGPT & Claude is

On a YouTube page, the extension shows a summary with clickable timestamps and a copyable transcript, and it can also summarize web articles and PDFs. Users choose ChatGPT, Claude, Gemini, or Mistral models and can adjust summary length and the prompt; chatting about content needs a free Glasp account with monthly credits.

Permissions and privacy

Page access

To summarize, the extension reads the YouTube page and its transcript, and its article and PDF modes read whatever page you invoke them on. If you mainly want video summaries, restrict site access to youtube.com in Chrome's extension settings and allow other sites on click.

Data notes

The listing discloses personally identifiable information and website content. Transcripts and page text are processed by the AI model you select, and chat history ties to your Glasp account once you sign in, so avoid summarizing private or unpublished material.

Pricing

Free summaries and transcripts; Glasp account for chat, with paid plans for more credits. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
