LingoAI Downloads & RevenueLingoAI: Offline AI Translator · App Store

Translate anything, anywhere. The complete AI translation model comes inside the app, so LingoAI works offline from the very first launch — nothing more to download.

The model runs on your iPhone. There is no account to create, and on-device translations never leave your phone. It is just as fast in airplane mode, deep in the subway, or abroad without a data plan.

NEW: THE LINGOAI KEYBOARD
Type in English, Chinese (Pinyin), Spanish, French, German, Russian or Korean, with accents on long press for other Latin-script languages. Turn on Full Access and the keyboard translates as you type, right inside Messages, Mail or any other app — then replace your text, append the translation, or copy it.

Why Full Access? Apple's on-device translator only works in keyboards that have it. The LingoAI Keyboard contains no network code: nothing you type is sent anywhere or stored. Without Full Access it still works as a normal keyboard.

TRANSLATE
Type, paste, dictate, or point the camera at a sign, a menu or a page. Lift text out of a photo, or import a .txt or Markdown file. Add more target languages to compare several translations side by side, and listen to either side read aloud at the speed you like.

RELAY
For talking with the person in front of you. Each of you speaks or types in your own language, and every message appears translated in one shared conversation you can both read and hear.

CHOOSE YOUR ENGINE
• LingoAI Model (default) — best for long sentences and idioms, fully on-device
• System — Apple's on-device translation, near-instant for short phrases
• Cloud (optional, off by default) — translates a whole document in one pass so names and terms stay consistent, offers a formal or casual tone, and adds 75 more languages. Text is sent to LingoAI's server only when you pick Cloud, and it uses credits.

FEATURES
• 38 languages on-device, 113 with Cloud
• Voice input with automatic language detection
• Live camera scan and text from photos
• Natural speech playback, through the speaker or privately
• Searchable history with copy, share, replay and delete
• Presets for the language pairs you use every day
• Themes and appearance options
• Designed for iPhone and iPad

FREE AND PRO
Free covers the everyday: translations up to 2,048 characters, camera scan, voice input, speech playback, full history, the LingoAI Keyboard, and one text relay plus one voice relay session.

LingoAI Pro is a one-time purchase — never a subscription — and unlocks:
• Unlimited relay sessions
• Long-text translation past 2,048 characters
• Saved translation presets
• No ads
• 500 Cloud credits, included once

Each unlock can also be bought on its own, and Pro includes premium features added later. Cloud credit packs are sold separately and never expire; a short sentence uses 1 credit.

GOOD TO KNOW
• The keyboard translates with Apple's on-device engine, so it covers the languages Apple supports, and a language may need a one-time download in iOS Settings.
• iOS always switch
