YouTube Summarizer

AIProductExtension

AI-powered YouTube summary tool — from idea to launch in 24 hours.

A speed-to-market experiment proving that a designer with AI tools can concept, design, and ship a complete product in 24 hours. Built to solve information overload for long-form video content — both as a browser extension and a content aggregator site.

24-Hour Delivery


With AI assistance, I completed the site's framework design directly in the IDE, launching in just 1 day.
For the browser extension, I quickly prototyped in Figma, generated style code, and handed off to frontend for logic and publishing.

Intuitive In-Page Interaction


Directly on the YouTube video page, users get a one-click summary including key takeaways, viewpoints, and timestamped segments for quick navigation.
An "Open in New Window" button bridges the extension to the aggregator site, encouraging users to explore more curated content.

Structured Information Design


Structure: The "Summary-Viewpoint-Detail" hierarchy aligns with user intuition, turning lengthy videos into scannable, structured insights instantly.
Efficiency: For users who find video watching too slow, the aggregator site presents valuable content in a blog-style waterfall flow, significantly boosting information acquisition efficiency.
