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.
What is Sumi - AI Manga Translator?
Sumi translates manga, manhwa, and webtoon images for readers. It detects original text, removes the lettering, restores the artwork underneath, and re-typesets the translation inside the image instead of covering panels with generic boxes. Vertical Japanese layouts remain vertical. It translates Japanese, Korean, and Chinese source pages into 16 languages. Visitors can translate a first page without an account; free accounts start with five pages and can claim five pages per day. Pro costs $6.99 per month or $69.99 per year. Sumi only translates pages the user provides and does not host, index, or crawl manga.
How we scored Sumi - AI Manga Translator
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 and cons
What we liked
- 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.
Where it falls short
- 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.
