About

Kanji Reader

Features
Read full description

Point your camera at Japanese text and read it right away. Kanji Reader is a furigana app for people learning Japanese: scan a textbook page, a manga panel, a sign or a letter, and every kanji reading appears in hiragana above the line. WHAT IT DOES • Scan and read — take a photo or pick one from your photo library. OCR pulls out the Japanese text and AI writes furigana over the kanji, like 調(しら)べます. • Understand the meaning — tap Explain and AI tells you what the passage actually says, in your own language. Grammar, context and background, not just the readings. • Hear it — tap play and listen to the Japanese out loud while you follow the text. • Scan several pages at once — do a whole chapter instead of one photo at a time. • Copy the text — one tap puts the extracted Japanese on your clipboard. STUDY WITH BOOKS Anything you scan can be bound into a Book. Pages keep their order, get a table of contents, and turn like a real book so you can read them again tomorrow. Export a Book as a PDF and take it to your tablet or e-reader. PRACTICE PROBLEMS Choose chapters from a Book and AI writes short written-answer questions from that exact text. Read the question, think, then turn the page for the answer and the explanation. You practise on the Japanese you actually care about instead of someone else's word list. GOOD FOR • Learning Japanese from a textbook or workbook you already own • Reading manga, novels, games and song lyrics in the original • Living in Japan: mail, forms, notices, menus, station signs • Japanese work documents, slides and handouts • Anyone who speaks some Japanese but gets stuck on kanji Free every day: 1 scan and 1 explanation. Premium removes the daily limits, lifts the caps on books and practice problems, and unlocks PDF export.
