Show, tell, or shake
Scan a word, describe what's coming up, or shake your phone. Dexy wakes up either way.
Built in Tokyo
Turn anything into a language lesson

How it works
From anything in your life to a lesson in your Dex
Four steps. A word you saw, a situation you're heading into, or a surprise from Dexy.
Get a 12-round lesson
Match, fill in the blanks, build sentences, and speak out loud. A full lesson, not a definition.
Review until it sticks
Spaced repetition brings each word back right when you need it.
Collect it in your Personal Dex
Every word you catch joins a growing record of the language you've met in real life.
Three ways to start
Show it. Tell it. Shake it.
Other apps hand you their word list. WordDex builds lessons from your life: the menu you couldn't read, the interview you're nervous about, the topic you're obsessed with this week.
Scan a word in the wild
Point your camera at a menu, a sign, or a manga page. WordDex reads it and builds the lesson around the word you pick.
Describe a situation
Type "ordering coffee," "my flight got cancelled," or "dinosaurs." If you care about it, it counts as study material.
Wake up Dexy
Shake your phone and Dexy, your sleepy little lesson-maker, wakes up with a surprise lesson from your interests and learner profile. He doesn't mind. It's the only way to wake him.
Why WordDex
Your words, not ours
The vocabulary that sticks is the vocabulary you actually meet. Everything you learn is something you'll see again.
Practice before it happens
Describe a date, a doctor's visit, or a hotel check-in. Get the key phrases, a model dialogue to rehearse, and teacher-style advice, tuned to a learner profile you can view and edit anytime.
Learning feels like playing
Matching games, timed Match rounds, sentence building, and streaks. Consistency is rewarded, not perfection. Miss a day? Dexy napped too.
Speak, don't just tap
Voice practice in every lesson builds the habit of using the language, not just recognizing it.
Word Scope
Go deeper on any word: real conversational usage, grammar, tone, and what a native speaker would say instead.
