Summarize Vid

About

Summarize Vid gives you a clean, readable summary of any YouTube
  video in one click — without leaving the page.

  Open a YouTube video, click the Summarize Vid icon, and a side
  panel shows the video's title and a Summarize button. Click it and
  you'll get a structured summary in seconds.

  FEATURES
  • One click — summarize the video in your current tab, no
  copy-pasting links.
  • Side panel UI — read the summary alongside the video.
  • Remembers your summaries — reopen the panel on a video you've
  already done and the summary is there instantly.
  • Clean formatting — headings and bullet points, easy to skim.

  HOW IT WORKS
  Sign in at sumvid.app, then click Summarize on any
  youtube.com/watch page. The extension sends only the current
  video's URL to sumvid.app to generate the summary — no browsing
  history, no other tabs, nothing sold or shared.

  Requires a sumvid.app account.
