Speak your first Japanese words today. PUCHI turns Japanese into a few happy minutes a day. Tap a word, hear it out loud, say it back, and a fluffy little study buddy cheers you on. No grammar drills, no overwhelm, just the words you will actually use. SAY IT, AND PUCHI LISTENS Every lesson ends with you speaking. Say the word, then the polite sentence, and speech recognition checks your pronunciation as you talk, with the live transcript right on screen. Get it right and Puchi celebrates with you. 2,060 WORDS YOU WILL ACTUALLY HEAR 25 themed chapters and 103 bite-size lessons take you from hai and arigatou through food, travel, work, feelings and city life. Twenty words a lesson, so you always finish what you start. HEAR IT IN A VOICE YOU LIKE Every word plays out loud in a natural Japanese voice, woman or man, your choice. Hiragana and romaji sit right under the word so you are never left guessing. Slow the audio down when a word ties your tongue in knots. SEE HOW IT IS REALLY USED Every single word comes with two example sentences, one casual and one polite, so you learn when to say it, not just what it means. A QUIZ THAT KNOWS WHAT YOU FORGET Smart Review comes back every day with the words you have studied and quietly gives extra practice to the ones you keep missing, until they turn into your strong points. Questions alternate between typing and speaking, so you train reading and pronunciation together. Type in hiragana or romaji, whichever you are ready for. A REASON TO COME BACK TOMORROW Set a daily goal, build a streak, and finish the day's mission to feed your puppy a treat. It is a small thing. It is also why you will still be here next month. LOOK ANYTHING UP Search all 2,060 words in Japanese or English, star your favorites, and watch vocabulary learned, quizzes taken and mastery climb on your profile. STUDY ANYWHERE Words, examples and audio all live inside the app, so a subway tunnel or a long flight is no problem. No account, no sign-up. Free to download. Built for absolute beginners, and designed with love by a small Japanese-led team.
