Select reading text and click the small icon, or press Ctrl+X (⌘X on Mac). Copying alone never starts a lookup. Cut stays unchanged in input fields and editors.
Your DeepSeek key and preferences stay on this device. Update your key through API settings. No DeepSeek website tab or website login is needed.
Explanations and News need an internet connection and a valid DeepSeek API key. Explanations are AI generated; check news dates and original sources.
Normal webpages are supported. Browser pages, the Chrome Web Store, PDFs, input fields and document editors are outside this version’s scope.
