About Zloth

AI-powered YouTube summaries — right from the thumbnail. We get it—there's too much video content and not enough time. Zloth is a Chrome extension that lets you summarize any YouTube video without even opening it. Every summary is saved to your browser, organized in folders, and ready when you are.

Our Mission

Video has become the world's classroom. From tutorials and lectures to documentaries and thought leadership—knowledge lives on YouTube. But watching everything takes time you don't have.

We built Zloth to bridge that gap. Our goal is simple: help you extract maximum value from video content with minimum friction. Whether you're a student researching for a paper, a professional staying current in your field, or a curious mind exploring new topics—Zloth lets you learn on your terms.

Who It's For

  • Students: Quickly review lecture recordings, research videos, and educational content.
  • Professionals: Stay up-to-date with industry talks, webinars, and conference recordings.
  • Knowledge Seekers: Scan through hours of interviews, podcasts, and documentary footage.
  • Lifelong learners: Explore new topics without committing hours to every video.

What Makes Us Different

  • Summarize from the thumbnail: No need to open the video first. The "Summarize" button appears right on YouTube thumbnails — decide what's worth watching before you commit.
  • Your personal summary library: Every summary is saved to your browser. Organize them in folders, sync across devices, and revisit anytime — even offline.
  • Timestamped insights: Jump directly to the moments that matter with clickable timestamps.
