What does Sumi do?

Sumi is an AI manga translator that erases the original text from manga pages and re-typesets your chosen language directly into the artwork. It works as a free Chrome extension, an online translator on mangasumi.com, and a native app for iPhone, iPad, and Apple Silicon Macs. You can try a single page translation without signing up, and the app handles whole chapters with a shared library across devices.

The tool stands out because it removes the original lettering cleanly rather than pasting white boxes over it, and it supports true vertical typesetting for Japanese, Chinese, and Korean tall speech bubbles. On iPhone and iPad, you can download model packs and run the entire translation pipeline offline — detection, reading, translation, and erasure all happen on your device. The model lab lets you pick between faster or higher-quality models depending on whether you're bingeing or savoring a page.

Sumi is built for manga readers who want to read official chapters in their own language without leaving the publisher's site. It's also useful for language learners who want to compare translations with the original text. The free tier gives you one page without an account, and signing up unlocks 15 free pages plus 5 more each daily check-in. Pro subscription costs $6.99/month for 1,500 pages of web translation, and the iOS app has a separate one-time buyout for unlimited offline use.
