Nihontekini
Claude connectorCommunityBuild Japanese flashcard decks, get quizzed on the words you keep forgetting and track your progress in the Nihontekini app.
Nihontekini connects Claude to your Nihontekini account, the iPhone app for learning Japanese with Anki-style flashcards and FSRS spaced repetition.
What Claude can do:
- Build decks: add words from a topic, a JLPT level, a text, song lyrics or a photo of a menu or sign. Readings, English meanings and example sentences you leave out are filled in from the JMdict dictionary, and words already in the deck are skipped.
- Quiz you: multiple-choice quizzes on the words you keep forgetting, mixing meaning, word and reading questions. Your answers are saved to the app's test history.
- Show your progress: words started and known, reviews due, and your weakest words.
- Fix cards: correct a reading, meaning or example, move cards between decks, suspend words you already know, or delete cards (Claude asks before deleting).
- Look up words in JMdict by kanji, kana, romaji or English.
Changes reach your phone the next time the app syncs.
Plans: studying your own cards is free. On the free plan, AI agents can add 50 cards and make 3 quizzes a month. Premium, bought in the iPhone app, removes those limits. Claude can tell you what is left but can't change your plan.
You sign in once with your email and a one-time code, and can revoke the connection any time in the app under Me > AI agents. The iPhone app is in early access and coming soon to the App Store.
