Learn Japanese, Korean, Chinese, Spanish, French, German & more with fun, game-like lessons — built from the real world around you. WordDex is the language app where anything you see can become your next lesson: scan any word and it turns into a full 12-round interactive lesson with matching, fill-in-the-blank, sentence building, and speaking practice. Other apps hand you their curriculum. WordDex builds one from your life — the menu you couldn't read, the sign on the train, the manga page on your desk. Every lesson trains real skills: vocabulary, grammar, reading, and speaking out loud. Built in Tokyo by a language learner who needed this app to exist. HOW IT WORKS See a word in the wild — on a menu, a sign, a manga page Scan it with your camera WordDex builds a 12-round interactive lesson around it: match, fill in the blank, build the sentence, say it out loud Review with spaced repetition until it sticks — then it joins your Dex WHY WORDDEX? Learning feels like playing. Every word becomes a game — matching, sentence building, timed Match rounds, streaks, and badges. Consistency gets rewarded, not perfection. Your words, not ours. The vocabulary that sticks is the vocabulary you actually meet. WordDex builds lessons from the words your real life serves you, so everything you learn is something you'll see again. Speak, don't just tap. Voice practice is built into every lesson — say the word, build the habit of actually using the language, not just recognizing it. Understand, don't just memorize. Word Scope takes any word deeper — real conversational usage, grammar context, tone and idiom analysis, and what native speakers would say instead. Collect your progress. Every word you catch becomes an entry in your Personal Dex — a growing record of the language you've met in real life. Spaced repetition brings the right words back at the right time. Start free, every day. Scan, learn, and review at no cost. START BEFORE YOU EVEN SCAN Free beginner decks for every language — turn them into full lessons the same way you would a word from the wild.
