AI Video Summarizer
Condense long videos into key points and takeaways with AI. Start with a free transcript — no account required.
Free · No sign-up · Requires retrievable captions
Long video, short read
Video is a poor format for reference. It is linear and harder to skim or search on its own. A summary plus searchable caption text makes a recording easier to use as a source.
JumpWatch currently works with supported YouTube videos whose captions it can retrieve. Paste a link above for the free caption text, or add the extension and sign in for AI summaries and chat subject to plan limits.
Structured, not vague
Key points and sections rather than a single generic paragraph that could describe any video.
Timestamped
Every point maps back to a moment in the video, so the summary doubles as a table of contents.
Interrogable
Ask follow-up questions about the video instead of re-watching to find one detail.

Video summarizer FAQ
What videos does this work with?
Public YouTube videos that have captions, including creator-uploaded and auto-generated ones.
Is there a length limit?
JumpWatch does not advertise a fixed duration limit. Longer videos can take longer, and success still depends on caption availability and service or upstream limits.
Does it work on other platforms?
Not yet. JumpWatch is focused on YouTube, which is where its transcript and on-page summary features are deepest.
Do I need an account or an extension?
No account or extension is required for the public transcript tool, which is free and subject to rate and capacity limits. The JumpWatch Chrome extension is free to install; its AI summaries and chat require sign-in and follow your account's plan limits.
