WordDex

You've built the habit. You've done the beginner lessons. But you still can't read a menu, a sign, or a page of native text without reaching for a translator.
WordDex picks up where textbook apps leave off. Point your camera at real-world text and it instantly creates an AI-powered flashcard with translation and reading — no typing, no copying, no "I'll look it up later." Your flashcards are always front and center——ready to review whenever your day gives you a moment.
Built by a language learner and solo dev in Tokyo.
GO DEEPER WITH WORD SCOPE
Tap any word for an AI-powered deep dive — how it's used in real conversation, why it matters grammatically, and words native speakers would reach for instead. Nuanced tone analysis and idiomatic explanations, not just dictionary definitions. The difference between knowing a word and understanding it.
BUILD YOUR OWN LIBRARY
Every word you scan becomes part of your personal collection. Spaced repetition brings the right cards back at the right time. Test yourself with the built-in Match game — tap to pair words with their meanings before time runs out. Daily streaks and badges reward consistency, not perfection.
EXAM-READY FROM DAY ONE
Pre-loaded JLPT and TOEIC decks — curated vocabulary so you can start studying before you even open the camera.
15+ LANGUAGES
Japanese, Korean, Chinese, Spanish, French, German, Arabic, Hindi, Italian, Portuguese, Russian, Thai, Vietnamese, Tagalog, and Esperanto. One app for every language you're learning. More to come!
BUILT FOR ACCURACY
