Why Ysum?
🧠
Instant value scores
Every YouTube thumbnail gets a usefulness score powered by AI.
⏱
Save your time
Stop guessing what’s worth watching — skip the fluff.
🎯
Personal AI logic
Coming soon: your own scoring logic based on your goals.
Visual sense filter
Ysum instantly scans every YouTube thumbnail and shows a usefulness score — helping you avoid low-quality content and skip the mental noise. The red–green–blue score system turns your feed into a signal map: what’s trash, what’s decent, what’s truly worth watching.

Review your memory
Your watched videos turn into memory anchors: searchable summaries, timestamps, and smart highlights. It’s like spaced repetition for your YouTube habits.

Personalized Lens
Everyone’s definition of “value” is different. With Ysum’s upcoming Persona Engine, you’ll be able to tune the scoring model to your goals: student, creator, strategist, explorer. See only what matters to your brain.

How it works
Each video has a short summary and a badge — how much useful values video gives.
