Latest version
Version 0.9.23
Released Oct 21, 2026 - 1.85 MBWorks with firefox 128.0 and laterNew: pick how Sumi looks — choose a skin for the floating Sumi and the translation balloons.
After a couple of successful pages, Sumi may occasionally ask if you'd like to rate the extension (Rate, Later, or Never).
If a translation really fails, a short "Having trouble?" line links to support.
The balloon close (×) now sits inside the bubble on every skin, so it's easier to hit and never covers the text.
Uninstalling opens a short, optional feedback form so we can learn what went wrong.Source code released under All Rights Reserved

Version 0.9.21
Released Oct 16, 2026 - 1.23 MBWorks with firefox 128.0 and laterTranslate no longer spends a page on a picture Sumi has already translated. Press Translate again on a finished page and Sumi tells you the page is already translated instead of buying it a second time. Re-translate still gives you a fresh translation when you ask for one.
Selecting a translated picture now translates the original, not Sumi's own lettering.
The image hover buttons can be turned off per site in Options.
The upgrade screen is now fully translated into German, Spanish, French, Italian, Portuguese, Japanese and Korean.
Alt+T now works on every page you turn to, not just the first one after the page loads.Source code released under All Rights Reserved

Released Sep 1, 2026 - 1.16 MBWorks with firefox 128.0 and laterThe "How's the translation?" prompt now waits for a natural stopping point (like finishing a chapter) and appears at most three times ever.

Version 0.9.16
Released Aug 25, 2026 - 1.16 MBWorks with firefox 128.0 and laterYour daily free pages are now claimed with a button, instead of arriving on their own.
• The account row in the popup gains a "Claim 5 pages" button whenever
today's free pages are still waiting. Signing in is required.
• Anonymous use is unchanged: one free page a day, no account needed.
• Corrected the free-tier wording in all 37 languages — 5 free pages when
you sign up, then 5 more each day to claim.Source code released under All Rights Reserved
Version 0.9.15
Released Aug 24, 2026 - 1.15 MBWorks with firefox 128.0 and later• All plans on the paywall: Pro, Pro+ and Studio side by side with
monthly/yearly pricing — pick the tier that fits how much you read.
• The interface now speaks 37 languages, and every target language in the
menu also shows its own name (e.g. "Japanese (日本語)"), so you can find
yours no matter what language the UI is in.
• Reliability fixes for re-shown translations: a previously translated page
can no longer be painted onto a different page after chapter navigation,
free replays keep working with auto-translate after you turn the page,
and very tall pages now say clearly when they can't be captured instead
of silently retrying.Source code released under All Rights Reserved
