About Sumi – AI Manga Translator

Sumi is an AI-powered manga translator designed to let readers enjoy manga, manhwa, manhua, webtoons, and doujinshi in their own language without leaving the page they are reading. Instead of uploading entire chapters to a server, Sumi works directly in the browser or app, translating the page currently on screen. It detects text in speech bubbles, erases the original lettering, redraws the artwork underneath, and typesets the translated text back into the bubbles—including native vertical typesetting for CJK languages. The tool is available as a browser extension for Chrome, Edge, Firefox, and Safari, as an online translator, and as a dedicated app for iPhone, iPad, and Mac. It supports over 130 languages and has been tested against 30 official manga platforms.

Sumi is built for readers who want a seamless reading experience without white boxes or awkward overlays. The translation happens in seconds per page, and an Auto mode can translate each page as you turn it. The Apple app includes a library feature that can import PDF, ZIP, CBZ, or EPUB files and translate whole chapters, with the option to run fully offline using models of your choice. The service appears to operate on a freemium model: users can start without an account, receive a limited number of free pages, and can claim additional free pages daily. A paid tier, Sumi Pro, is advertised starting at $6.99 per month, though exact limits and features should be verified on the official pricing page.
