Read raws like they were
translated all along.

MangaLens watches your screen while you read manhwa, manga or manhua in any app, finds the speech bubbles, wipes them clean and re-letters them in English — live, hands-free, like a human scanlation.

IT'S OKAY. I'LL PROTECT YOU. …THANKS, HYUNG.
What you read — cleaned and re-lettered, live

How it works

  1. Start MangaLens and allow screen capture. A small floating 文A button appears — tap it any time to toggle translation.
  2. Read normally in Brave, Chrome, or any reader app. When you stop scrolling for a third of a second, MangaLens finds the speech bubbles in the pixels — round ones, spiky shout bubbles, black narration boxes, tinted pastel ones.
  3. The bubbles become English. Each balloon is wiped to its own paper color through its exact detected shape and re-lettered in comic type with a letterer's line taper. Scroll on and overlays clear instantly; pages you've read re-paint from cache at no cost.

Why it feels different

◐Cleaned, not covered

No translucent boxes floating over text. The original lettering is gone — wiped through the balloon's own detected mask — and the English is typeset in its place.

⚡Live & hands-free

No screenshotting, no share-menu, no cropping. Stop scrolling and the page translates itself; scroll and it gets out of your way.

🔒Private by default

Capture and OCR run entirely on your device. The free engine sends only bubble text. Optional AI Vision sends the page image — only to the provider you chose.

✨AI Pro, your key

Bring a free Google AI Studio key and the AI reads whole pages with story memory, a persistent name glossary, honorifics and natural tone. A live model picker always offers Google's newest Flash models.

🧠Remembers the story

Character names, pronouns and running jokes stay consistent across pages, chapters and restarts — scoped per series, so stories never contaminate each other.

🌏KO · JA · ZH → EN

Korean webtoons, vertical Japanese, simplified and traditional Chinese — plus raws that are secretly Spanish or English uploads. It reads what's actually on the page.

Install in two minutes

  1. Download MangaLens.apk on your Android phone or tablet.
  2. Open the file. Android will ask you to allow installs from your browser — that's the standard prompt for any app outside the Play Store. MangaLens is open source; you can read every line on GitHub or verify the download against the release checksums.
  3. Open MangaLens → grant "Display over other apps" → Start translating. The app checks for new versions by itself and offers them in-app.

FAQ

Is it really free?

Yes. The default Google engine and the offline engine cost nothing and need no account. AI Pro mode uses your own API key — Google AI Studio keys have a free tier that's plenty for reading.

Does my reading leave my device?

Screen capture and OCR are 100% on-device. The free engine sends bubble text only; AI Vision mode sends the page image to the AI provider you picked, and nowhere else. No analytics, no tracking, no account.

Which apps does it work with?

Any app that shows a page — browsers, reader apps, galleries. Private/incognito tabs block screen capture by design (the capture shows black), so use a normal tab.

Overlays don't appear?

Check that "Display over other apps" is granted, and that you're not in a private tab. The in-app Diagnostics toggle shows exactly what was detected if something looks off.

Battery?

Use "Tap to translate" mode — capture idles until you tap the floating button.
