Kontx

Get the full picture from every video. Real-time context cards explain people, jargon, and concepts as you watch.

Ever watch a YouTube video and hear a name, term, or reference you don't recognize — but don't want to pause and Google it? Kontx fixes that. Kontx watches along with you. When someone drops a name you've never heard, uses jargon from another field, or references an event they assume everyone knows — a small card quietly appears in the sidebar with exactly the context you need. No pausing. No tab-switching. No losing your train of thought. It works like a friend who knows a lot sitting next to you, whispering "that's the CEO who got fired last year" or "that's a term from options trading — here's what it means" at just the right moment. HOW IT WORKS 1. Open any YouTube video with captions 2. Click the Kontx icon 3. Cards appear at the exact moment each topic comes up in the video 4. Dismiss what you already know — save what you want to remember IT LEARNS WHAT YOU KNOW Dismiss a card once and it's gone forever. Over time, Kontx stops showing you things you've already learned. Select the fields you want covered — Tech & AI, Business, Science, Health, Culture, History, Sports, and more.
