Sumbox - YouTube & web summarizer

Sumbox summarizes YouTube videos and web articles in seconds — right inside Chrome's side panel. Click Summarize on any video or article, and get structured insights without leaving the page. 🎯 WHAT YOU GET Every summary is structured into clear sections so you can go as deep as you need: 1. TL;DR — Bullet-point highlights of the most important takeaways. Perfect for deciding if something is worth your full attention. 2. Summary — A comprehensive narrative covering all major points. Understand the full picture without watching or reading. 3. Formatted Script (YouTube videos only) — A clean, readable transcript with clickable timestamps. Click any timestamp to jump directly to that moment in the video. ⚡ BUILT FOR SPEED Sumbox uses parallel processing to deliver results up to 5x faster than traditional summarizers. Long video? Sumbox splits the transcript into chunks, processes them simultaneously, and stitches the result together — typically in under 10 seconds, even for hour-long videos. 🌐 14 LANGUAGES SUPPORTED Summarize content in any language and get results in your preferred language.
