Sumi Pro — one subscription for the web and the extension
v3.0.0One subscription covers the online translator and the Chrome extension, and billing moved from per-tab to per-image
2026/07/27
Sumi Pro
- $6.99/month — every page you translate in the online translator and the Chrome extension, on one account, up to the fair-use ceiling below
- $59.99/year if you would rather pay once, which works out to $5.00/month
- Cancel in two clicks from Settings → Credits. Cancelling keeps your access until the end of the period you already paid for — nothing is cut off early
- Fair use is printed on the card: 1,500 pages per rolling 30 days. Normal reading is nowhere near it, and going past it falls back to any page credits you have rather than stopping you mid-chapter
Still free to start
- One page in the browser with no account at all
- 30 more free pages when you sign up — no card
A page now costs a page
Web and extension translation used to be charged once per browser tab. A chapter is one tab with dozens of images, so a whole chapter cost a single credit. Charging now keys on the image itself. Translating the same image twice is still charged once.
Page packs are retired on the web
The web sells one thing now. Credits you already bought are untouched, never expire, and still spend — they are used whenever a subscription is inactive or past its fair-use ceiling.
The iPhone and iPad app is unchanged: no subscription there, just page packs and the one-time offline buy-out.
Sumi 1.0 — seamless manga translation reader
v1.0.0Bring your own chapters and read them in your language — original text erased, translation re-typeset into the art
2026/06/01
Highlights
- Seamless translation: Sumi erases the original text from the artwork and re-typesets your language in its place — no boxes pasted over the art
- True vertical CJK: Tall bubbles get native vertical Japanese, Chinese, and Korean, read top to bottom like the original
- Bring your own manga: Import PDF, ZIP, CBZ, EPUB, photos, or whole folders — with drag-and-drop on iPad. Sumi never hosts or crawls manga
- Read offline: A $9.99 one-time buy-out downloads the model pack and translates unlimited pages on your iPhone or iPad — no credits, no connection
- Learn as you read: Tap a word for the built-in dictionary, save it to flashcards, and review with spaced repetition
- Ebooks too: Read your own ebooks with furigana, right next to your manga
Pricing
- Your first 10 pages are free
- Page packs: $1.99 for 200, $5.99 for 1,000, $12.99 for 3,000 — no subscription
- $9.99 one-time offline buy-out on iPhone and iPad
Sumi runs on iPhone and iPad, and installs on Apple Silicon Macs from the Mac App Store — the same reader, with menu bar shortcuts and drag-and-drop. On Mac, translation runs via the cloud.
