OpenKoto
OpenKoto is a language-learning app for turning content you choose into reading and study material. It imports URLs and PDF, EPUB, TXT, Word, and Markdown files, then provides automatic translation and vocabulary extraction. In the reader, learners can switch languages in real time, look up words, and parse grammar. An AI assistant offers contextual word explanations, grammar breakdowns, pronunciation guidance, and questions about highlighted text. The app supports learning and transcription in more than 100 languages, including Japanese, English, Chinese, Korean, French, German, Spanish, Italian, and Portuguese. The maker also describes video learning with synchronized subtitles and transcription. Desktop downloads are listed for Mac, Windows, and Linux; native iPhone and iPad apps include offline-first use, vocabulary review, and video subtitles. The maker says desktop data is processed locally and iOS learning data stays on the device, with API keys in the iOS Keychain. OpenKoto is free and open source under Apache 2.0. Its web version is being rebuilt, with vocabulary review, novels, and lyrics planned to sync across platforms.
