## What is AI Japanese?

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.

## Version history (last 5 releases)

### 1.3.2 — 2026-10-01

· You can now look up words or full sentences selected directly in the scan screen.
· Added English and Italian interface support, as well as Japanese language learning.
· Fixed quiz grading to distinguish voiced kana sounds (such as "がっこう" vs. "かっこう").
· Other minor improvements and fixes.

### 1.3.1 — 2026-09-25

· Chapters in the Audio tab are easier to use. The current chapter name is always shown, with buttons to skip to the previous or next chapter, and the chapter list opens as a sheet so you can read the headings.
· The default pause length used to split chapters is now 0.5 seconds, so chapters can be made from conversation material with short gaps (change it under Settings › Audio).
· Fixed an issue where the screen could stop responding after creating chapters while playback continued.
· Creating chapters a second time no longer re-reads the audio, so it is faster.
· Transcription of long recordings (over 10 minutes) is now split into parts.
· Fixed the play button not working after a track ended.
· Fixed listening questions sometimes not playing from the start of the clip.
· Quiz fixes: double-tapping a button no longer skips a question, the answer field is no longer hidden behind the keyboard, choices that could be guessed by elimination are no longer offered, and answers containing commas are graded correctly.
· Fixed backup restore losing data or overwriting newer content. The daily reminder is re-registered to match the restored settings.
· Fixed some text that stayed in Japanese when the interface was in English.
· Improved the Pro purchase screen: you can reconnect when the price cannot be loaded from the App Store, and fixed the screen sometimes becoming unresponsive after a purchase.
· Removed the API key field. All AI features now work through the app's built-in service with no setup (any key you registered before is deleted).
· Other minor fixes.

### 1.3.0 — 2026-09-16

· The app is now available in English. It follows your device language, and you can switch it by hand under Settings › Display and study.
· Explanations, summaries and questions from the AI are written in the language of the interface, so an English interface gives you English explanations.
· Added a "How to use" page under Settings covering each tab, the trial and Pro, and how your data is handled.
· You can now photograph a textbook page after page. The shots are gathered into a single note, so one summary and one set of questions cover the whole passage.
· Choose how deep an explanation you want — Simple, Normal or Detailed. The choice is remembered per note, so it can follow how hard the material is.
· Added Scan, which straightens a photographed page and trims away the desk around it (Pro).
· Quizzes now give you a box to type the answer in. Checking it marks you right or wrong, and you pick the review interval after seeing that result.
· The test that opens right after you create questions from a note now has the same answer box.
· Conversation questions still work by self-marking against a model answer — there is no single right way to say something, so they are not marked automatically.
· Note photos can be reordered, so pages taken out of sequence can be put back in order.
· Notes can be tagged, and the list can be filtered by tag.
· Export the questions from a single note to Anki, so you can keep a deck per book.
· Words picked out of a photo in the Search tab can be turned straight into a note.
· Save a word from an explanation onto the note, where it is kept as a related word.
· Statistics now include a score per note, worst first, so it is easier to decide what to study next.
· Backups can include the note photos themselves, so they survive moving to a new phone.
· Fixed the price shown in Settings and on the trial-ended message: it now always uses the price from the App Store for your country, instead of a fixed Japanese price.
