Thaluna: Screen Translator

Thaluna is an OCR screen translator for games, manga, visual novels and other on-screen text. Use it as a game translator for dialogue and menus, or a manga translator for speech bubbles. Select a screen area and read translations over the original text with Game Lens or beside it with Nearby Lens.

TRANSLATE GAME TEXT WITHOUT MODIFYING YOUR GAME
Choose the language visible on screen and the language you want to read. Start screen sharing and select the dialogue or subtitle area once. Thaluna follows changed text automatically. Use on-screen translation for RPG dialogue, turn-based games, visual novels and readable menus. Compatibility depends on the app, capture restrictions and text layout.

TWO WAYS TO READ TRANSLATIONS
Game Lens places a translation overlay over detected text. Tap Original to reveal the source; translations stay hidden for later dialogue until you show them again. Processing continues while hidden. Nearby Lens keeps the original visible and places captions beside it. Unlock to adjust the reading area or move and resize Nearby captions. Change text size and appearance in Settings. Minimize hides controls and area outlines; Pause stops processing; Stop ends screen sharing.

MANGA AND COMICS
Translate visible manga dialogue and comic text in a selected screen area. Zoom small speech bubbles before selecting them for more readable OCR text recognition. This reads the page displayed on your phone; it does not import or translate entire books automatically. Decorative fonts and vertical or very small text may be difficult to recognize.

OFFLINE SCREEN TRANSLATION
Basic Offline translates text on this phone after the required language packs have been downloaded. Download the packs with internet first, then use offline translation without API credits. Quality varies by language pair and source text. Google ML Kit sends its own SDK diagnostics and usage metrics, not your OCR text or screenshots.

OPTIONAL AI TRANSLATION WITH OPENROUTER
Use your own OpenRouter API key and selected model for cloud translation. Internet and separately billed API credits are required. Only recognized or entered text is sent after your consent, not screenshots. OpenRouter and model providers have their own terms and data policies. Buying Thaluna Pro does not include OpenRouter usage.

FREE AND PRO
Free includes 30 successful translation batches per day. A batch can contain several OCR boxes. Empty input and failed translations do not use the allowance. Unchanged recognized text is not repeatedly charged within the same running app; recognition changes and restarting the process can count a new batch.
Pro is a one-time Google Play purchase removing Thaluna's daily limit for both engines. No subscription or ads. Google Play shows the local price before purchase. Restore purchase uses the purchasing Play account after reinstalling.

SCREEN SHARING AND HELP
Allow overlays and approve sharing only the app or screen you intend to translate. Android 14+ single-app sharing helps exclude Thaluna overlays. Entire-screen capture and older devices may flicker. Protected screens may be blank; Thaluna does not bypass restrictions. OCR may miss rapidly changing text. Use only content you are permitted to translate.
Help contains setup instructions, tutorials, privacy information, licenses and voluntary diagnostic-report export. Reports are not sent automatically. Interface: English. Intended for adults (18+).
