# Sumi - AI Manga Translator Review

An AI-powered tool that erases original manga lettering and re-typesets translations directly into the artwork for personal reading.

## Editor's Score: 82/100

Sumi delivers a unique in-place re-lettering feature and supports vertical CJK layouts and batch translation, earning strong capability and ease-of-use scores. Value is lower because page-count limits and separate mobile pricing create friction for heavy users. Delivery is solid with offline mode and tested platform coverage, though lack of team features holds it back slightly.

## Pros
- Re-typesets translations directly into the artwork, preserving vertical CJK layout and bubble shapes.
- Supports batch translation (up to 20 pages at once) and works on 110 tested official manga platforms.
- iOS app offers offline translation via a one-time model pack buy-out.

## Cons
- Monthly page-count limits (1,500 to 12,000) can restrict heavy readers unless they pay for top tiers.
- iOS app pricing and page-pack model differ from web version, which may confuse users.
- No team or multi-user collaboration features, designed strictly for personal use.

## Verdict

Best for readers who want clean, in-place translations of manga, manhwa, and webtoons with support for vertical CJK typesetting and batch processing. The trade-off is that heavy readers hit page-count limits unless they pay for high-tier plans, and the mobile app’s pricing and offline model differ from the web version. If you need unlimited or team-scale translation, consider Canva’s Magic Studio for broader design use.

Best for: Personal readers wanting immersive, re-lettered manga translation.
Not for: Heavy or team users needing unlimited or scalable translation.

## Overview

Sumi is a reader-focused AI tool that automates the scanlation pipeline: it erases original lettering and re-typesets translations directly into the artwork, preserving vertical CJK layouts and bubble shapes. It works via a web translator, Chrome extension, or native app on Apple devices, and supports batch translation of up to 20 pages at once.

It supports Japanese, Korean, and Chinese source text and translates into over 134 languages, tested on 110 official manga platforms. The iOS app adds offline translation via a downloadable model pack and page-pack purchases, while the web version relies on cloud translation with monthly page-count tiers.

## Who should use it

Anyone who reads raw manga, manhwa, or webtoons and wants a clean, immersive translation experience without white boxes or sidebars. It’s ideal for solo readers who value visual fidelity and vertical typesetting. Heavy readers or small teams who need unlimited or collaborative translation should look elsewhere. Canva’s Magic Studio offers broader design and text tools that may better suit scalable workflows.
