Nofy | Your vocabulary, built as you browse

Look up English words and save vocabulary right in your browser

Build English vocabulary from the pages you already read. Look up words in context, save what matters, and review on a schedule—without leaving your flow. WHAT YOU CAN DO • Look up words and short selections on any page via a lightweight tooltip—definitions, phonetics, and audio when available. • Use smart hotkeys for instant translation: press Shift once to translate selected text, or press Shift twice quickly to open an input box for custom translation. • Save words to your personal list with translations and context you care about. • Highlight saved words on pages or optionally replace them with English to reinforce recognition while you read. • Review vocabulary with spaced repetition–style practice and optional daily reminders (notification or open review). • Open a dedicated vocabulary view from the toolbar or new tab to study, practice, and track progress. • Optional sign-in unlocks sync and AI tutor features where enabled for your account. Core vocabulary saving works locally without signing in. WHO IT’S FOR Learners who want vocabulary that grows from real reading—not from yet another disconnected word list. PRIVACY & DATA How Nofy uses data is described in our privacy policy and the Chrome Web Store privacy disclosures. Sign-in and sync are optional; core saving works locally in your browser. Install Nofy if you want English vocabulary that stays with you as you browse.
