What it does
YouTube Summary with ChatGPT & Claude is a Chrome extension from Glasp Inc. that turns long videos and pages into short summaries. Open a YouTube video, click the extension icon in the browser toolbar, and it generates a summary of the video along with the transcript when one is available. Summaries can be shown with or without timestamps, and clicking a timestamp jumps to that part of the video. A Copy Transcript button puts the full transcript on your clipboard. The same approach works for web articles and PDFs you are reading. The summarizing is powered by ChatGPT (OpenAI), Claude (Anthropic), Mistral AI and Google Gemini; the listing does not say whether you can choose between them. In the extension settings you can change how long the summaries are and edit the prompt used to produce them. The listing says it handles videos in several languages and lets you pick the transcript language. The listing describes it as a free extension and also notes that it offers in-app purchases, without saying what they cost.
