Dokkai is a mobile application designed to help users learn Japanese by scanning and translating Japanese text from images. It provides furigana readings, vocabulary definitions, grammar explanations, and allows users to save words for flashcard study.
How does Dokkai's translation feature work?
Dokkai uses advanced OCR technology to extract text from images of books, manga, signs, menus, or subtitles. It then provides AI-powered translations that aim for natural language understanding rather than just word-for-word conversion.
