MangaTranslate uses a pipeline of AI models running in your browser and on our servers:

1. Bubble detection identifies speech bubbles in the manga page
2. OCR (text recognition) extracts the original text from each bubble
3. Language detection selects the correct OCR model (Japanese, Korean, or Chinese)
4. AI translation converts the full page of text into your target language
5. Inpainting removes the original text and fills with the background
6. The translated text is rendered directly into the cleaned panels

The whole process takes under 5 seconds for a typical manga page on the first load. Previously translated pages load in under 2 seconds from cache.

MangaTranslate currently works on 9+ sites:

• • MangaDex
• • MangaPlus
• • Kakao
• • Naver
• • Asura Scans
• • MgEko
• • ManhwaClan
• • RawKuma
• • Manhwa18

New sites are added regularly. Check the extension Settings screen for the current list. If your site isn't supported, email us at [email protected] to request it.

MangaTranslate works on Chromium-based browsers:

• • Google Chrome (v110+) — fully supported
• • Brave — fully supported
• • Microsoft Edge — fully supported

Firefox and Safari are not supported at this time. MangaTranslate is a Manifest V3 Chrome extension.

Limited support on Chrome for Android. Chrome Android supports extension installation via the Kiwi browser or via developer mode on some devices. The experience is not optimized for mobile viewports. Full mobile support is planned for a future release.

Common causes:

• • No bubbles detected — the page may not have detectable speech bubbles, or the image quality is too low
• • Backend unreachable — our server may be temporarily unavailable; try again in a few minutes
• • Quota exceeded — you've hit your monthly image limit; purchase a credit pack or upgrade your plan
• • Page not supported — the current site may not be in our supported list

Check the progress overlay in the extension popup for a specific error message.

Some bubbles may be skipped if: the OCR extracted no readable text (blank or stylized font), the text is too small for accurate recognition, or the bubble detection confidence was too low. Sound effects (onomatopoeia) in highly stylized fonts are often skipped intentionally — they are hard to translate meaningfully.

Yes. Click any translated bubble in the page to open an edit field. Type your correction and press Enter. Your edits are saved locally using a perceptual hash of the bubble's visual content — so corrections persist across sessions and on identical pages. Your corrections are never sent to an AI model.

You can translate from Japanese, Korean, and Chinese into any language supported by the Gemini API — including English, Spanish, French, German, Portuguese, Indonesian, Vietnamese, Thai, and dozens more. Set your target language in the extension Settings screen.

Open the extension popup → click your email address → click "Manage Subscription." This opens the Stripe Customer Portal where you can upgrade, downgrade, or cancel. Upgrades take effect immediately (with prorated credit). Downgrades take effect at the start of your next billing cycle.

Cancel anytime from the Stripe Customer Portal (Settings → Manage Subscription). You'll retain access until the end of your current billing period. You will not be charged again after cancellation. You can also email [email protected] and we'll process it within 24 hours.

Contact [email protected] within 7 days of a charge for a refund. After 7 days, no refunds are issued for partial billing periods except as required by law. Credit packs are non-refundable.

All major credit and debit cards via Stripe: Visa, Mastercard, American Express, Discover. Apple Pay and Google Pay on supported browsers. We do not accept PayPal at this time. All transactions are processed securely by Stripe — we never handle your card details directly.

No. Manga page images are processed ephemerally — they exist in server memory only for the duration of translation (typically under 10 seconds) and are never written to disk or stored in any database. A numeric perceptual hash (pHash) of text regions is cached in Redis for 7 days to avoid re-translating identical pages. The original image cannot be reconstructed from this hash. See our Privacy Policy for full details.

We collect: your email address (via OAuth), translation usage counts, timestamps, and subscription status. We do not collect your browsing history, reading history, location, or advertising identifiers. Payment data is handled entirely by Stripe — we never see your card number. See the full Privacy Policy.

Open the extension popup → Settings → "Delete Account." This will cancel your Stripe subscription, delete your account from our database, and purge your Redis cache. This is permanent and irreversible. Alternatively, email [email protected] and we'll process the deletion within 5 business days.

Try these steps in order:

1. Confirm the site is in our supported sites list
2. Reload the page and try again (Alt+T or click the extension icon)
3. Check that the extension has permission for this site: click the puzzle icon in Chrome toolbar → MangaTranslate → "Allow on this site"
4. Disable other extensions temporarily to check for conflicts
5. Update the extension to the latest version via chrome://extensions

If the issue persists, email us with the site URL and browser version.

First translation of a new page can take up to 5 seconds — this is expected. If translation is consistently slower than 10 seconds, it may indicate: high server load (try again in a few minutes), a large page with many bubbles, or a slow network connection. Cached pages should always load in under 2 seconds. If slowness persists, email us with your extension version and approximate timing.

You've used all your monthly images. Options:

• • Wait for your quota to reset at the start of next month
• • Purchase a credit pack ($2.99 / 100 images) from the Settings screen (Starter, Pro, Premium only)
• • Upgrade to a higher tier from Settings → Manage Subscription

Chrome may have hidden the extension from the toolbar. Click the puzzle piece icon (Extensions) in the toolbar and pin MangaTranslate. If the extension doesn't appear at all, go to chrome://extensions to verify it's installed and enabled. If it's missing entirely, reinstall from the Chrome Web Store.
