## What is Zenzu?

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
