About Zenzu: AI Language Mastery
Zenzu transforms the way you learn languages. Instead of artificial exercises and gamified drills, you learn from real-world content — YouTube videos, articles, and photos from your daily life. HOW IT WORKS Import any content you find interesting — a YouTube video, a news article, or even a photo with text. Zenzu's AI breaks it down into meaningful vocabulary and phrases, creating personalized learning material just for you. SMART SPACED REPETITION Powered by the FSRS-5 algorithm, Zenzu schedules your reviews at the optimal moment — right before you'd forget. Every review session is efficient and builds lasting knowledge. LEARN YOUR WAY • Import YouTube videos with subtitles and learn from real conversations • Snap photos of menus, signs, or book pages to capture new vocabulary • Import articles and let AI extract key words and phrases • Review with intelligent spaced repetition that adapts to your memory BUILD YOUR FUTURE, STEP BY STEP Zenzu is not a game. It's a serious tool for people who want real language skills. Every deck you create is a tree in your personal grove — watch your knowledge forest grow as you progress. FEATURES • AI-powered content import (YouTube, articles, photos) • FSRS-5 spaced repetition algorithm • Beautiful forest-themed progress visualization • Works offline after content is imported • Support for any language pair
