I Built a YouTube Extension. People Download It All Over the World

Description and use

A Chrome extension that instantly summarizes long YouTube videos and articles, offering concise points, full subtitles, and additional features like translation and history.

Problem

Users spend long time watching or skipping long YouTube videos and other long texts because they cannot quickly grasp the main points.

Outcome

The extension is downloaded worldwide, with users from the US, Europe, Asia, and Latin America, providing a free AI-powered summary without ads.

Workflow

• Open a long YouTube video or article
• Click the extension button or press Alt+S
• The extension fetches subtitles or page text
• Generates a concise list of main points
• Displays full subtitle text if available
• Allows translation, history access, and question answering

Evidence

I built it for myself. I thought it would stay a small tool “for me and people like me.”

After I published it on the Chrome Web Store, installs started coming from all over — the US, Europe, Asia, Latin America.
