KanjiAI: Kanji & Japanese Reading

Master kanji. Read real Japanese. Build toward JLPT N4 to N1 — all from one free app.

A flashcard loop that actually works Set your lesson range, choose your parts of speech, and study the exact vocabulary you've been taught. Type the reading in kana or romaji, hear natural audio on every card, and mark words you've truly mastered so they fade into the background.

Go deeper with the Top 10,000 Words When you're ready to push further, turn on the Top 10K toggle to add high-frequency vocabulary up to approximately JLPT N1 — but only words that use kanji you already know. No surprises, just natural expansion.

Tap any kanji. Go deeper. Every kanji on every card is a link. Tap it to open its full detail page — see how it breaks down into components, explore its on and kun readings, find the phonetic component that explains why it sounds the way it does, and read the mnemonic that makes it stick. Navigate recursively through every component.

Read real Japanese — at your level Every unit has three AI-generated reading passages built from vocabulary you already know. A focused unit passage, a daily life scene, and a short narrative. Each passage includes:

Furigana toggle — show or hide readings Colour-coded kanji so you instantly see what you know vs. what's new Tap any word or kanji for its meaning Grammar cards explaining the patterns used, with real sentence examples Read-aloud with word-by-word highlighting Everything is pre-generated and fully offline — no API key, no internet required.
