What is YouTube Spoiler
Spoil any YouTube video from the thumbnail — before you click. Kill clickbait in ~2 seconds. Free. Summarize any YouTube video in ~2 seconds — without opening it. Hover over a thumbnail, click Spoil, and get AI bullet takeaways. Built for skipping clickbait, not for another watch-page summarizer.
WHAT MAKES YOUTUBE SPOILER DIFFERENT? Most YouTube summarizer extensions need you to open the video first. YouTube Spoiler works from the thumbnail on Home, Search, Subs, sidebar, and more. Hover, Spoil, decide — no extra tabs, no paste-a-URL loop.
HOW IT WORKS 1. Hover any YouTube thumbnail — a Spoil badge appears 2. Click Spoil — AI reads the captions and streams key takeaways 3. Read, copy, or skip — in seconds, not minutes
FREE AND PRO
- Free: 3 spoils per day — enough to try it as a daily habit
- Pro: $3.99/month for unlimited spoils (Stripe)
- Google sign-in is used for daily limits and Pro — we do not track your YouTube watch history
