What it does

YouTube Summary with ChatGPT & Claude is a Chrome extension from Glasp Inc for condensing videos, articles and PDFs. The store listing says the summaries are powered by ChatGPT from OpenAI, Claude from Anthropic, Mistral AI and Google Gemini. On a YouTube video you click the extension icon in the toolbar and it generates a summary, with or without timestamps. Clicking a timestamp jumps to that part of the video. When a transcript is available it is offered alongside the summary, and a Copy Transcript button puts it on the clipboard. You can change the summary length in the settings, customise the prompt used, and choose the language of the transcript. The listing says it handles videos in several languages. The listing describes it as free and notes in-app purchases. It names research, studying and learning as typical uses.
