  description

  Listen. You're not on YouTube to waste your life in a 47-minute intro before someone gets to the point.
  
  You're there to learn. Decide. Ship.
  While everyone else is still scrubbing the timeline like it's 2011, you're already done.
  
  SummarizAI is your unfair advantage on every YouTube watch page.
  
  One click. One panel. One clean AI summary — chapters, key ideas, and the moments that actually matter. No new tab. No copy-paste circus. No "I'll watch it later" graveyard.
  
  
  THE PROBLEM (YOU KNOW IT)
  
  • 40-minute video. 90 seconds of gold buried at minute 38.
  • You skip. You miss the point. You watch it twice anyway.
  • Your time is worth more than a creator's 8-minute sponsor read.
  
  Stop donating hours to the algorithm.
  
  
  WHAT YOU GET — RIGHT ON YOUTUBE
  
  One-click Summarize
  A Summarize button sits next to Share — exactly where your thumb already lives.
  
  Chapters & key ideas
  Structured sections you can scan in under a minute. The cliff notes — without the guilt.
  
  Clickable timestamps
  See something worth hearing? Tap. Jump. Play. No manual scrubbing. No guesswork.
  
  Comment insights
  When captions aren't enough, we surface themes from top comments so you catch what the crowd noticed.
  
  Your language
  Summaries follow your language preference. Read it the way you think.
  
  Works when captions are missing
  No transcript? We can fall back to audio transcription (plan limits and processing time apply).
  
  Stay on the watch page
  The summary panel lives beside the video. You don't leave YouTube. You leave the time sink.
  
  
  WHO THIS IS FOR
  
  Students — Turn lectures and tutorials into exam-ready notes in minutes.
  Professionals — Extract decisions, quotes, and takeaways from talks and meetings. Skip the replay.
  Creators & researchers — Scan long videos for structure, hooks, and audience reactions fast.
  
  If YouTube is part of how you work, learn, or compete — this extension pays for itself on the first video.
  
  
  FREE TO START. NO EXCUSES.
  
  Free: 3 summaries per day. Sign in. No credit card. Try it on your next rabbit hole.
  Pro: Unlimited summaries, any video length, summary translations — for people who refuse to wait.
  
  Re-summarizing the same video the same day? Doesn't burn another free slot. We're not here to nickel-and-dime you for clicking back.
  
  
  HOW IT WORKS (STUPID SIMPLE)
  
  1. Add to Chrome
  2. Open any YouTube watch page
  3. Hit Summarize
  4. Read. Jump. Win your hour back.
  
  That's it. That's the whole pitch.
  
  
  THE BOTTOM LINE
  
  Every hour you lose to a video you didn't need to watch end-to-end is an hour you didn't spend building, studying, closing, or living.
  
  SummarizAI doesn't replace thinking.
  It replaces sitting through noise to find signal.
  
  Install it now. Open YouTube. Summarize the next video that looked "interesting" but felt "too long."
  
  Your future self will thank you. Your competition won't know what hit them.
