How it works

  • Shift

    Paragraph translation below the original

    Hover over a paragraph and press Shift (or another key you choose). Long paragraphs can be shown sentence by sentence — automatically, always, or never.

  • Control

    A word’s meaning in this sentence

    Hover over a word and press Control for a card with its meaning here, part of speech, base form and the phrase it belongs to. A short definition also appears as you hover, and double-click lookup can be turned on in settings.

  • Language chunks, if you want them

    Turn on Structure Analysis to underline useful phrases in translated paragraphs, each with its own short explanation.

  • Translation history in the side panel

    Your translations are listed in Chrome’s side panel, where you can play them aloud, open a sentence analysis, or delete them.

  • Cloud or on-device translation

    Cloud translation uses Microsoft Azure and Google Translate. Or switch to Chrome’s built-in translation model, which translates on your device. Word explanations use OpenAI and Google Gemini models.

  • Fits your browser

    Light, dark or automatic appearance, with a choice of highlight colors and underline styles.
