Transforming "I Can't Read" into "Learning" on the Spot. News, academic papers, social media, foreign books— The biggest obstacle to learning English is having to switch apps every time you encounter an unfamiliar word, which breaks your concentration. This app utilizes advanced character recognition technology to directly connect every word on the screen to your intelligence. ■ Three Core Features to Accelerate English Learning ・In-Screen AI OCR & Instant Translation Scan areas of interest while browsing. Eliminates the need to switch to a dictionary app, allowing you to read smoothly while maintaining context. ・Never Miss Text in Images and Videos Uses the standard iOS/macOS analysis engine. Accurately extracts text from social media posts that cannot be copied, subtitles in videos, and text in PDF documents. ・Multilingual Support for Over 20 Languages Supports the latest language engines supported by the OS, including English, Chinese, and Korean. Always provides highly accurate translation and recognition. *Supported languages vary depending on the OS version. Certainly! I have translated the tables into English and cleaned up the duplicates for you. ## Supported Languages | Language | Browser Code | Translation Code | | :--- | :--- | :--- | | English (US) | `en-US` | `en` | | English (UK) | `en-GB` | `en` | | Japanese | `ja-JP` | `ja` | | Chinese (Simplified) | `zh-Hans` | `zh-Hans` | | Chinese (Traditional) | `zh-Hant` | `zh-Hant` | | Cantonese | `yue-Hant` | `yue` | | Korean | `ko-KR` | `ko` | | French | `fr-FR` | `fr` | | German | `de-DE` | `de` | | Italian | `it-IT` | `it` | | Spanish | `es-ES` | `es` | | Portuguese | `pt-BR` | `pt` | | Russian | `ru-RU` | `ru` | | Ukrainian | `uk-UA` | `uk` | | Thai | `th-TH` | `th` | | Vietnamese | `vi-VN` | `vi` | | Indonesian | `id-ID` | `id` | | Turkish | `tr-TR` | `tr` | | Polish | `pl-PL` | `pl` | ### New in iOS 26 | Language | Browser Code | Translation Code | | :--- | :--- | :--- | | Dutch | `nl-NL` | `nl` | | Arabic | `ar-SA` | `ar` | | Hindi | `hi-IN` | `hi` | | Danish | `da-DK` | `da` | | Norwegian | `nb-NO` | `nb` | | Swedish | `sv-SE` | `sv` | ■ Enjoy even greater comfort on larger screen devices ・iPad / Mac: The large screen allows for in-depth learning by displaying the original text and translation side-by-side. ・iPhone: Due to screen size, single-screen mode (not split-screen mode) is recommended. ■ Recommended for: ・Those who want to efficiently read the latest news and technical articles from overseas. ・Those who want to learn "authentic expressions" directly from social media and videos. ・Those who want to enter a reading flow state without being interrupted by the hassle of "looking things up." ■ Terms of Use https://www.anotherbrain.co.jp/terms/oju
