AI Japanese: Notes & Quizzes

Photograph a page and it becomes a Japanese lesson. Look a kanji or word up and several AIs answer at once. No sign-up, the first 10 uses are free with every feature, and if you keep it, you pay once — there is no subscription. ■ Turn a textbook or your notes into a study note Photograph a lesson, a handout, manga or your handwriting and the Japanese text in the picture is transcribed, and you can correct anything misread on the spot. Explanations add kana readings in the form 漢字（かな） and romaji for the headword. One tap adds a summary and an explanation covering grammar, vocabulary, nuances and cultural background. Tap any word or kanji to dig into it. Choose how many questions and how hard, and test yourself on that lesson straight away. Notes link to each other, so you can be tested across related notes. ■ Ask several AIs, not one Claude, Gemini and others answer the same question side by side. Where they agree and where they differ is visible, giving you confidence and nuance that a single AI chat cannot provide. Meaning, readings (in the form 漢字（かな）) and romaji, etymology, kanji breakdown, and two conversation examples — casual and formal — come as standard. ■ Everything you study becomes review material Related words become questions on their own. Spaced repetition (SM-2 or Leitner, your choice) brings them back just before you forget, and anything you mark “Again” returns until it sticks. Graded with exact kana matching so you never confuse voiced sounds. Export to Anki when you want to. ■ Listening, from your own material Import audio by scanning a QR code in your book or from files on your device. Playback continues with the screen off and can be controlled from the lock screen. Mark an A-B range and turn it into a dictation question — each review plays exactly that range. Transcription turns a recording into text you can look words up in. ■ Languages Learn Japanese, French, German and Spanish with Pro (or during your trial). Italian and English are included as standard. The interface is available in English, Japanese and Italian and follows your device setting. ■ About using it No API key is required. The first 10 uses give you every feature, and buying Pro (one payment) keeps it going, with a monthly usage cap and a curated set of models. The words and images you enter are sent through OpenRouter to the AI providers to generate explanations; you are asked before this happens the first time. On the trial and Pro these go through our relay server, which does not store what you send. It only records the operational data described in our privacy policy (an anonymous device token, usage counts and the data needed to verify a purchase). Your history and notes are stored only on your device.
