You've done the streaks. You've drilled the vocab lists. You still freeze when someone speaks to you. knockOut builds lessons around your vocabulary — not a preset curriculum. AI. Comprehensible input. Real progress. HOW IT WORKS You pick your words. The AI generates full lessons around them — reading passages, listening exercises, context-rich content built for your level and interests. As you read and listen, you naturally encounter new words and concepts. knockOut tracks them. Next session, those words come back — woven into new content, reinforced through context. Not dumb buttons. Not drilling. The language builds itself into you, the way it's supposed to. WHAT MAKES IT DIFFERENT • Lessons built around your vocabulary, not ours • New AI-generated content every session • 6-level mastery system — not streak counters • No gamification. No fake progress. • Works for any language, any level Serious learners. The kind who've been burned by apps that turned language learning into a mobile game. If you want an app that congratulates you for opening it, this isn't it. If you want to actually speak the language — start here.
