Sumi translates manga, manhwa, manhua, webtoons, comics, and doujinshi directly inside the artwork. It detects text, reads the source language, erases the original lettering, and places the translated text back with vertical Japanese, Chinese, and Korean typesetting.
The service is available on the web, as Chrome, Edge, Firefox, and Safari extensions, and through iPhone, iPad, and Mac apps with offline support. Users can translate individual images or chapters in PDF, ZIP, CBZ, and EPUB formats, add glossaries, and use Auto mode while reading supported websites.
