Sumi: AI Manga Translator

Sumi is an AI-assisted manga reader for chapters, ebooks, images, and web pages you have the right to read.

Most translators paste white boxes over the art. Sumi detects the original text, cleans the lettering area, and re-typesets your language where it was, vertical Japanese included. You can compare, edit, and keep reading in one place.

READ YOUR MANGA IN YOUR LANGUAGE • Import PDF, ZIP/CBZ, EPUB, MOBI/AZW3, photos, or folders • Open web pages in Sumi's in-app browser and translate page images in place • Original text areas are cleaned and re-typeset over the page • Tall bubbles keep vertical CJK typesetting • Long-press to peek at the original; tap a bubble to retranslate or fix • Webtoon mode, double-page spreads, and full-immersion reading

LEARN WHILE YOU READ • Tap words for reading + meaning with a downloadable offline dictionary • Save words to your deck and review with spaced repetition • Furigana support for EPUB, MOBI, and AZW3 ebooks

CHOOSE CLOUD OR OFFLINE • Cloud translation sends page or bubble images to Sumi's translation service after a one-time consent prompt • Offline mode downloads a model pack once and translates on device • When you choose offline translation, no page images leave your device

FAIR, SIMPLE PRICING • Your first 30 pages are free • Then buy page packs — from $1.99 for 200 pages. No subscription • Pages only count when a translation succeeds; credits never expire • Or unlock unlimited offline translation once, forever

BRING YOUR OWN CHAPTERS Sumi does not host, crawl, or provide manga. Import files you legally own, or browse sites where you have the right to read the content.

Works on iPhone, iPad (with drag-and-drop import and keyboard shortcuts), and Apple Silicon Macs.
