The translation, right where the original text was. Play a Japanese game, read a Chinese comic or browse an overseas shop, and OS Translator reads the text on your screen and translates it on the spot. While you use any other app, OS Translator reads your screen and shows the translation in a Picture in Picture window. When the screen changes, the translation follows within about a second. No screenshots, no copy and paste. TWO WAYS TO READ • Mirror mode — Place the PiP window at the top or bottom of the screen, and it mirrors the other half with the translation laid over the original text. Speech bubbles and product pages read just as they look. • Subtitles mode — Game dialogue, menus, chat and captions burned into videos appear as a list in the PiP window, starting with the paragraphs closest to what you're reading. • On iPad, put another app next to OS Translator in Split View or Stage Manager. The app mirrors it and lays the translation right over the original text. HOW IT WORKS • Pick the language to read and tap Start Translating. • Share your entire screen when iOS asks, then go to your game, comic or app. • Move and resize the translation window as you like. Stop anytime from the app or the screen recording indicator. GREAT FOR • Dialogue and quests in Japanese games • Manga, webtoons and web novels that haven't been translated yet • Product names, options and details in overseas shops • Social media and forums in other languages • Captions burned into videos ALSO • Reading direction for vertical manga • Choose whether to show the original text • Recent Translations keeps what you read so you can view and copy it again EVERY FEATURE FREE No limits on time or number of translations, and every feature is free. A short ad may play before you start translating. The only purchase is Remove Ads — buy once and it's yours for good. TRANSLATED ON YOUR DEVICE Reading the screen and translating both happen on your device with Apple's built-in text recognition and translation. What's on your screen is never sent anywhere or saved. Once a language is downloaded, translation works even in Airplane Mode. LANGUAGES Translate between 20 languages, including English, Japanese, Korean, Chinese (Simplified and Traditional), Spanish, French, German, Portuguese, Russian, Arabic, Hindi, Thai, Vietnamese and more.
