Screen Translation
Translate text on any screen in real time. Works with any app — games, social media, web browsers, documents, and more.
How It Works
Setup — Choose Your Settings
Source Language (From)
The language of the text on your screen that you want to translate. For example, if you're reading a Japanese game, select Japanese as the source language.
Target Language (To)
The language you want the translation to appear in. For example, select Thai or English as your target language.
OCR Engine (Text Recognition)
Start the Translation Service
Tap the Start Button
After selecting your languages and engines, tap the Start button on the Home screen.
Grant Permissions
The first time you start, Android will ask for Screen Capture and Display Over Other Apps permissions.
Privacy Note
Screen images are processed on-device for OCR. Only the extracted text is sent to the translation engine. Images are never stored or sent to any server.
Using the Floating Button
Switch to Any App
Once started, a floating button appears. Switch to any app you want to translate — a game, LINE, Twitter, a web browser, a PDF, anything.
Tap to Translate
Tap the floating button once to capture, read all text with OCR, translate, and show the result as an overlay.
Move the Button
Drag the floating button to any position. You can also hide it at the edge and double-click to show it again.
Reading the Translation
Translation Overlay
The translated text appears directly on your screen as a semi-transparent overlay over the original text.
Dismiss the Overlay
Tap anywhere on the overlay or tap the floating button again to dismiss and return to normal view.
Auto Mode (Advanced)
Auto Mode automatically captures and translates at regular intervals (0.5 to 60 seconds). Useful for games, videos, and live content.
Note: Auto Mode uses more battery and, if using Coins-based engines, will consume Coins for each capture cycle.
Area Selection (Advanced)
Select a specific area to translate instead of the entire screen. Useful for game dialogue boxes or specific UI sections.
💡 Tips for Best Results
Face-to-Face Translation
Have a real-time conversation with someone who speaks a different language. You speak — the app listens, translates, and speaks the translation aloud.
How It Works
Both directions work — each person speaks their language and hears the translation in theirs.
Choose Translation Mode
MC Mode Free
Completely free and works offline. Uses built-in speech recognition, offline translation, and device voice output.
COINS MODE

Tip: Auto Language Detection
In COINS and Custom modes, the app can automatically detect which language is being spoken and route it correctly.
