Images Upscale verdict
Images Upscale is the right pick for occasional users who need a fast, no-install way to sharpen a handful of images each day without paying anything. The free tier is genuinely useful, but 2 credits per day is a hard ceiling that makes it impractical for anyone processing more than a few files regularly. If you need batch volume or API access, look elsewhere.
Strengths
Genuinely free daily use with no watermark: 2 credits per day require no account and produce clean downloads, which is a real differentiator from tools that watermark free output.
Four content-specific upscaling modes (Photo, Anime, Product Shots, Screenshots/UI) let users match the model to the image type rather than applying a single generic pass.
Weaknesses
2 credits per day is an unusually tight free ceiling: most comparable tools offer at least 3 to 5 free runs per day or a monthly credit pool, so anyone with even modest regular needs will exhaust the free tier quickly.
No published subscription tier names or monthly plan prices on the pricing page, only a per-credit rate starting at 3.8 cents. Buyers cannot compare a monthly cost against competitors without doing extra math or contacting support.
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.
