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. You can compare, edit, and keep reading in one place.
IN YOUR OWN SAFARI
• A Safari extension ships inside Sumi — nothing else to download
• Open the manga site you already use, tap Sumi, read it in your language
• Your tabs, logins and bookmarks stay exactly where they are
• One page balance shared between the app and Safari
• Turn it on once: Settings › Apps › Safari › Extensions › Sumi
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
• Optional vertical CJK speech bubbles can be enabled in Translation settings
• 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
• 15 welcome pages free, then +5 more every day you check in
• Sumi Pro includes 1,500 cloud pages per rolling 30 days — pages come back one at a time as they age out, so there is no reset date to wait for
• Prefer to pay as you go? Page packs are available, and those pages never expire
• Pages only count when a translation succeeds
• 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.

1. Click to import the folder 100% flashback2. Clicking to delete all local data in the settings will cause the app to be unable to use next time, and the white screen will flash back.3. Click the import symbol on the comic tab. There is no return key. You must import it to go back. Click to view all without a return key.4. The imported comics are not edited in the comics tab, cannot be deleted, and cannot be read.5. Comic translation cannot be freely selected whether to translate or not. After importing, the translation will start automatically and cannot be suspended.6. The translation heat is too serious, the power drops too fast, and the equipment may be seriously stuck, which needs to be optimised.7. I hope to provide emails or add a telegram group in the app to facilitate feedback.
