Start the Translation Service

Start Button

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.

3

Using the Floating Button

Floating Button on screen

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.

4

Reading the Translation

Translation Overlay

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 toggle

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)

Area Selection

Select a specific area to translate instead of the entire screen. Useful for game dialogue boxes or specific UI sections.

💡 Tips for Best Results

Use the right OCR engine
MC Mode Free is fast for most languages. Switch to COINS MODE for handwriting or unusual fonts.
AI engines for context
COINS MODE (AI Translation) understands context better. Great for games, slang, and natural conversation.
Brightness matters
OCR works best on clear, well-lit screens. Increase brightness if text recognition is poor.
Save Coins with Area Selection
When using Coins-based engines, select only the area you need to translate instead of the whole screen.
👥

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

🧑
Person 1 speaks Thai
↓ Speech-to-Text → Translate → Text-to-Speech ↓
👩
Person 2 hears English
↓ Speech-to-Text → Translate → Text-to-Speech ↓

Both directions work — each person speaks their language and hears the translation in theirs.
