About RubiMask: Book Translator
Read books in any language — in your own language. Point your camera at a page, select a passage, and RubiMask translates it and reads it aloud. Tap any word to see what it means. Japanese novels, Chinese web fiction, English paperbacks, manga, textbooks, printed handouts: if it's on a page, you can read it. HOW IT WORKS 1. Scan a page with the camera, or open a photo or PDF 2. Drag over the passage you want to read 3. Listen to the translation — then tap words to learn them KEY FEATURES 【Translate Any Page】 - Detects the book's language automatically - Translates on your device with Apple's translation engine - Reads the translation aloud automatically, or plays the original for listening practice - Books already in your language are read aloud without translating 【Tap a Word, Get the Meaning】 - Every word in the passage is tappable - Shows the reading (hiragana for Japanese, pinyin for Chinese) and a quick translation - Look words up in the built-in iOS dictionary - On devices with Apple Intelligence, see what the word means in this exact sentence 【Made for Real Books】 - Built-in document scanner straightens and crops pages - Pinch to zoom in on small print, then select precisely - Vertical Japanese text supported, with furigana (ruby) ignored so it doesn't scramble the text - Save your book and pick up where you left off 【Furigana Masking & OCR Tools】 - Automatically mask furigana on vertical Japanese books - Extract text from PDFs and photos in many languages - Export as text, masked PDF, images, or audio (M4A) PERFECT FOR - Reading books in a language you're learning - Enjoying Japanese novels and manga before they're translated - Understanding textbooks, handouts, and printed documents - Listening to a page instead of reading it FREE & PREMIUM Free: 20 reads per day, and word meanings are always free.
