An interactive branching story where you generate the world, read in Japanese, tap for help, save words, and they return later in natural context—so they actually stick.
Every saved word returns later—inside branching scenes you helped shape—so recall becomes recognition, not guesswork.
Words due for review are softly highlighted inside the story so you naturally revisit them in context.
Tap any highlighted word to instantly see reading, meaning, pitch & usage—then grade it without leaving the scene.
Click any new word—slang, onomatopoeia, JLPT terms—to get a breakdown (reading, meaning, grammar) and add it to your deck mid‑scene.
Role‑play through choices that shift tone, politeness (敬語), and stakes—vocabulary reappears in fresh pragmatic contexts.
Automatically adjusts from beginner-friendly (N5) to nuanced N1 prose—controlling grammar density, register, and vocab complexity.
Not in the mood to role‑play? Pick from smart continuation options that reinforce targets while moving the plot forward.
