SCAN ANYTHING
Point your camera at books, manga, signs, menus, or subtitles. Dokkai instantly extracts the text using advanced OCR.
NATURAL TRANSLATIONS
AI-powered translations that sound natural, not robotic. Get the meaning, not just word-for-word conversion.
LEARN AS YOU READ
Every scan becomes a lesson:
- Furigana readings above kanji
- Vocabulary breakdowns with definitions
- Grammar explanations

BRING YOUR OWN MATERIALS
Study what YOU want to read — not textbook examples. Real Japanese content at your level.
LIBRARY
Read real Japanese — the way it was actually written.
Dokkai's Library is a curated collection of authentic Japanese content designed for learners. Short stories, diary entries, and dialogues written by real people, covering everyday life, culture, and the kind of Japanese you'll actually encounter outside a textbook.
Every piece in the Library comes fully equipped with the tools you need to understand it deeply:
Hard mode — read the raw Japanese and analyze any word you don't know with a single tap
Cheat mode — toggle furigana, read alongside the English translation, or challenge yourself with English-only and reveal the Japanese when you're ready
Study mode — break down every sentence with furigana, grammar patterns, and color-coded vocabulary cards
Content is organized by difficulty level (N5–N1) and format, so you can find something that matches exactly where you are right now. Series let you follow a story across multiple chapters, tracking your progress as you go.
New content added regularly.
iCLOUD SYNC
Your scans, vocabulary, and progress sync across all your devices.
SUBSCRIPTION

I’m a long suffering Japanese learner, the thing that always bugged me about taking online courses and lessons is that they wouldn’t have a way to translate what was being said or the grammar used in normal conversations outside of the main dialogue for that lesson. This app fixes that entirely. It is also what kept me from actually reading Japanese light novels or books, but this app not only translates the words, but it also shows the general grammar patterns being used, so instead of just reading the words you can actually understand the content. And that’s just the base stuff, I haven’t even looked at the reader and flashcards and other things, the core functions have supercharged my learning, and I finally feel like I’m understanding the language. 10 out of 10, would recommend.
Essential for learning
Global Kite
Learning Japanese means constant memorization of expressions and usages that vary depending on the context and situations. This app was essential for me to quickly build up my level by having all my past learnings at my fingertips. No more need to look back to search for something I learned a few months ago.
