Sumi - AI Manga Translator verdict
Sumi is the right pick for a reader who wants to follow Japanese, Korean, or Chinese titles without waiting for official translations, and who cares that the page still looks like a manga page rather than a document with text boxes pasted over it. The free tier is genuinely usable at 5 claimable pages per day, but the web and iOS subscriptions are completely separate, so a reader who switches between phone and browser will pay twice. Anyone who needs bulk export for fan releases or wants a tool that works across every device under one subscription should look elsewhere.
Strengths
Inpainting-plus-retypesetting pipeline produces pages that look drawn rather than overlaid, including vertical Japanese bubble layouts, which most generic image translators do not handle.
Tested and confirmed working on 110 named manga publisher sites, with the Chrome extension translating pages in place on sites like Shonen Jump+ and MANGA Plus without any file upload.
Weaknesses
Web and iOS subscriptions are completely separate with no shared page balance, meaning a reader who uses both the browser and the iPhone app must pay for two independent plans.
Source language support is limited to Japanese, Korean, and Chinese; there is no path to translate, say, a French or Italian doujinshi into English, even though the site mentions such use cases in its marketing copy.
Fudge verdict
Best for Shopify merchants who want to build or tweak pages by typing prompts and get clean, native theme code without bloat. It lacks a visual editor and Figma integration that competitors like Instant offer. If you prefer drag-and-drop or Figma workflows, look at Instant instead.
Strengths
Generates clean native Shopify theme code (Liquid, CSS, JS) with no app bloat or branding.
Design reference search and token extraction from real websites via Chrome extension.
Weaknesses
No visual drag-and-drop editor or Figma integration, unlike competitors like Instant.
Free tier only includes public DESIGN.md guides and extension - not page building features.
