What is it?

TranslationPlugin adds translation features to JetBrains IDEs and Android Studio. Developers can translate selected words or words under the cursor, replace identifiers with their translations (for example in camel case when the output is English), and view translated Quick Documentation and inline documentation without leaving the editor.

The plugin supports several translation engines, including Microsoft Translator, Google Translate, DeepL, OpenAI, Youdao, Baidu and Alibaba Translate, and can switch between them from the status bar. Text-to-speech is available through Microsoft Edge TTS, Google TTS and OpenAI TTS. It also includes a translation dialog, a word book and a word-of-the-day feature.

The plugin is compatible with a wide range of IDEs, including IntelliJ IDEA, PyCharm, WebStorm, GoLand, Rider, CLion, RustRover and HUAWEI DevEco Studio.
