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.
tradutor de mangá com IA verdict
Best suited for individual scanlators and small localization teams who need a browser-based pipeline that handles OCR, text removal, and retypesetting in one place. Compared to Sumi, it adds a fuller online editor and API access, but its credit model means costs scale quickly for anyone processing full volumes regularly. Casual readers who just want to read a chapter or two will find the free daily check-in credits thin and should look at Sumi instead.
Strengths
Full pipeline in one browser session: OCR, LLM translation, text removal, background repair, and retypesetting without any desktop software.
Tiered credit system with no expiry on one-time packs, so studios that translate in bursts pay only for what they use rather than a recurring seat fee.
Weaknesses
The free path is limited to daily check-in credits with no disclosed per-day amount on the pricing page, making it nearly unusable for anyone processing more than a handful of pages without paying.
Credit costs scale against you at volume: a scanlation group processing 500 pages per month at the Monthly subscription rate of 3,200 credits for $12.90 will exhaust credits quickly if each page consumes multiple credits depending on the chosen LLM model.
