About this app

Rasterdeck Translator is a fully offline translator with on-device AI. Speak, take a picture, or type, and translate without internet, without an account, and without your words ever leaving your phone.

Download your languages once, then translate offline anywhere: on a plane, on the metro, abroad without a SIM, or anywhere you simply don't want your conversations sent to a server.

VOICE TRANSLATOR: SPEAK AND TRANSLATE
Push-to-talk voice translation in 40 languages. Talk naturally and hear the translation spoken back. A real voice translator for face-to-face conversations, no internet connection needed.

PHOTO TRANSLATOR: TAKE A PICTURE, READ EVERY LINE
Take a picture of a menu, sign, or document and every line appears below the photo, translated next to the original. Tap any line to hear it spoken aloud in either language, so you can read a menu item back to a waiter. Picture translation runs completely offline, so it keeps working exactly where you need it most: deep inside a foreign supermarket with no signal.

VOICE CLONING (PRO)
The Pro tier clones each speaker's voice on the fly, in 28 languages, so the translation is spoken in a voice that sounds like you instead of a robot. All cloning happens on your phone. Your voice never leaves the device.

TEXT TRANSLATION: FREE FOREVER
Type-to-translate between 42 languages, free and unlimited. Your first 10 spoken translations are also free, so you can test real voice translation before paying anything.

PRIVATE BY DESIGN
No account, ever. No cloud. No tracking, no telemetry, no data collection. A private translator in the literal sense: after the one-time language download, nothing you say, photograph, or type leaves your phone. If you handle sensitive conversations, whether business, medical, legal, or just personal, this matters.

BUILT FOR TRAVEL
A travel translator that works with airplane mode on. No roaming data, no dead zones, no waiting for network while someone stands in front of you. Download your language packs on hotel Wi-Fi and you are set for the whole trip.

LANGUAGES

HONEST FINE PRINT
Language packs are a one-time download (internet needed just for that). The AI runs entirely on your phone, so recent mid-range or better hardware gives the best voice experience.
