Get the transcript free, then summarize it with AI
Paste a supported YouTube link above to get its available timestamped caption text, free and with no sign-up. That can be enough to search or skim a long video.
For an AI summary with key points, sections, and takeaways, add the JumpWatch Chrome extension. The extension is free to install; AI use requires sign-in, follows account plan limits, and depends on retrievable captions.
Key points with timestamps
Summaries link back to the moment each point was made, so you can verify anything that matters.
Chat with the video
Ask follow-up questions answered from the transcript instead of re-watching to find one detail.
Your choice of model
Send a supported video's transcript to ChatGPT, Claude, or Gemini if you would rather use your own assistant.
