## What is Sumi?

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.

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
• 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
• 15 welcome pages free, then +5 more every day you check in
• Pro: 1,500 cloud pages per rolling 30 days, monthly or yearly — 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 from $1.99 for 200 pages, 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.

### 3/5 — Ipad26.6bug, I use offline translation

*2026-08-11*

1. Click to import the folder 100% flashback
2. 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.

**Developer response:** Thank you for the detailed report. We are sorry for the trouble. Most of what you listed — the crashes, the missing back buttons, the problems with imported comics, and translation starting on its own — is already fixed in the update we are shipping next, and we are still working on the heat and battery drain.

If you run into anything else, or have suggestions for us, please write to hello@mangasumi.com or go to mangasumi.userjot.com. We read everything.

We will keep improving Sumi. Thank you for your support.

## Version history (last 5 releases)

### 1.0.10 — 2026-09-03

• New: Sumi Pro+ — 4,000 cloud pages every month for heavy readers
• Redesigned plans page: monthly or yearly at a glance, page packs a tap away
• Settings shows your plan and remaining pages on a live meter
• The in-app browser now guides first-time readers with real example chapters; Home returns you to Reading
• Subtle haptic feedback when a page finishes translating, a purchase goes through, or you claim your daily pages
• Fixes: Japanese vertical text stays inside its balloon, Restore Purchases and daily pages are more reliable, and opening Sumi from a notification no longer crashes

### 1.0.9 — 2026-08-18

• Offline translation, reworked: Sumi now auto-configures the strongest model your device can run — zero setup
• Model downloads are now several times faster on slow connections
• Fixed a crash that could occur when starting offline translation
• Language names now follow your app language
• Send feedback to us right from Settings
• Stability and polish throughout

### 1.0.8 — 2026-08-12

• Model downloads are now several times faster on slow connections
• Fixed a crash that could occur when starting offline translation

### 1.0.7 — 2026-08-02

Sumi has a Safari extension, so you can translate manga in your own Safari — on the site you already read on, with your tabs and logins untouched. It was buried; now it isn't. Settings has a Safari section that shows whether it's switched on, and "Open in Safari" offers the two one-time setup steps instead of dropping you into a Safari that can't translate.

A new sample chapter: original artwork drawn for Sumi, waiting on your shelf the first time you open the app.

Translation reliability: fewer speech bubbles come back empty, and a bubble with nothing written in it no longer gets an invented line.

Offline translation got a major quality upgrade: a new on-device engine now covers 11 languages, with cleaner phrasing and full-page context.

### 1.0.6 — 2026-07-26

What's new:
• Smoother, more reliable manga translation.
• Rate Sumi or send feedback right from Settings.
• Fixes and refinements throughout.
