About this extension
The extension automatically detects the language of selected text on a webpage and shows its translation, transcription, a contextual translation of the full sentence or paragraph, and audio in the original language. Open the translator instantly with a keyboard shortcut.

WHAT IS IT FOR?

1) Instantly translate unfamiliar words or entire sentences. Select text and get a translation. There is no need to copy it, open a new tab, and look for a translator or dictionary.

2) Translate your own text without leaving the current tab. Press a keyboard shortcut to open a pop-up translator and type or paste text.

3) Learn languages in context. When reading in another language, quickly check an unfamiliar word and keep reading. Save the word together with the context in which it appeared, without interrupting your reading to build a vocabulary list.

4) Build your own vocabulary. Automatically save useful information and export it to a file for making a vocabulary list or study materials.

PRIVACY AND DATA STORAGE

Translation history and settings are stored locally in your browser. To translate text and retrieve transcriptions, selected text may be sent to the translation services and dictionary sources used by the extension. These features require an internet connection.

The extension does not sell user data or use it for advertising, credit decisions, or purposes unrelated to its core features. You can delete individual entries or clear your history in the extension. To remove all history, settings, and local cache, uninstall the extension or clear its data using your browser.

Context Translator keeps the process simple: select text, understand it right away, and save the translation for future study when you need it.
