Sentence Hover Translator is a free Chrome extension designed to enhance your reading experience by providing instant translations. When users hover over a sentence, the extension automatically translates it, facilitating comprehension of foreign language content. This tool is particularly useful for those engaging with English web pages, as it is set to activate by default on all such sites.

The extension supports two modes to cater to user preferences. The first mode displays the original text while showing the translation upon hovering, while the second mode does the opposite, revealing the original text when hovering over the translation. Users can easily toggle the extension on and off using the Alt/Option + Z keyboard shortcut, making it a convenient tool for language learners and casual readers alike.
