Consume smarter. Not longer.
Ysum helps you watch with intent, not inertia — through AI-powered summaries, usefulness scores, and personalized viewing modes.
Why We Built Ysum
YouTube is the world’s biggest classroom — but it’s also the biggest distraction machine. We built Ysum to extract signal from noise. To make each watch session meaningful. No more doomscrolling. Just the insights, ready to apply.

How It Works
