About
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

【Made for Real Books】
