What Sumi is
Sumi is an AI manga translator that rewrites the text in manga and webcomics into the language you choose.

It is available as an app on iPhone, iPad, and Mac, as a browser extension for Chrome, Edge, and Firefox, and as an online version. It supports 134 languages and performs true vertical typesetting for Chinese, Japanese, and Korean text so the layout stays faithful. It starts free, with extra free pages after you register an account.

What to watch out for
It starts free, but free page limits and terms can change, so confirm current details before heavy use. Translation quality varies by language pair and by how busy the artwork is, so some panels may read rough. Only use it on content you are allowed to access and translate, and respect the terms of the sites you visit. Treat output as a reading aid rather than a polished official translation. Free tiers and usage limits can change, so check the current rules on the official page before relying on it long term. Processing speed depends on file size and network conditions, so retry later if a task stalls during peak hours.
