Google Translate is a free online translation service provided by Google. It supports translation between many languages, allowing users to translate text, websites, and even spoken words.

Mobile app: Google Translate is available as a mobile app for Android and iOS devices. With the app, you can translate text, speech, and even use your device's camera to translate text in images or signs.

Browser extension: Google offers a browser extension for Google Chrome that allows you to quickly translate web pages. Once installed, the extension adds a button to your browser toolbar, which you can click to translate the current page.

Speech translation: Both the web-based version and the mobile app support speech translation. Click the microphone icon in the input box (or tap it on the mobile app) and speak the phrase you want to translate. The translation will appear in the output box.

Camera translation: The mobile app allows you to use your device's camera to translate text in images, such as signs or menus. Tap the camera icon in the app, point your camera at the text, and the app will overlay the translation on the image.

Handwriting input: The mobile app also supports handwritten input. Tap the pen icon and write the text you want to translate on your device's screen. The app will recognize the text and provide a translation.

Offline translation: The mobile app allows you to download language packs for offline use. This is useful when you're traveling and don't have access to a reliable internet connection.

Please note that while Google Translate is a powerful tool, it may not always provide accurate translations, especially for idiomatic expressions or complex sentences. It's best to use Google Translate for general understanding and rely on professional translation services for critical or specialized content.
