Sumi

Sumi is an AI manga translator with full platform coverage — web tool, Chrome/Edge/Firefox/Safari extensions, and iPhone/iPad/Mac apps with offline translation. It detects text in manga, manhwa, webtoons and doujinshi panels, recognizes the source language, erases the original lettering, and re-typesets your language directly into the art rather than producing a separate transcript. Demonstration cases across Korean shōnen, romance fantasy and BL manhwa show the pipeline in action.

The re-lettering-into-the-art approach is what separates it from screenshot-plus-Google-Lens workflows — the output is readable as a comic, not as annotations beside one.

Who it's for: manga and manhwa readers following series not yet licensed in their language, scanlation-curious readers who want speed over typesetting perfection, and multilingual readers jumping between Japanese and Korean sources. Free to start, $6.99/month for volume. Translation quality on dense SFX-heavy pages varies — test on your actual reading list, and mind that translating unlicensed work for anything beyond personal reading steps into copyright territory.
