Dictionary Dad

Double-click any word for its definition. Save, highlight, and master vocabulary with spaced repetition.

Dictionary Dad is a beautiful, lightweight dictionary extension that helps you look up, save, and actually remember new words. 🔍 Instant Definitions Double-click any word on any webpage to see its definition in a gorgeous popup — with pronunciation, audio, examples, synonyms, and antonyms. No new tabs, no interruptions. ⌨️ Keyboard Shortcut Select any text and press Ctrl+Shift+D (Cmd+Shift+D on Mac) for an instant lookup. ❤️ Love & Save Words Found a word you admire? Love it. Want to remember it? Save it. Both collections are organized in the toolbar popup and a beautiful full-page gallery. ✨ Smart Word Highlighting Saved words are automatically highlighted on every webpage you visit — a constant, gentle reminder of words you're learning. Choose your highlight color and intensity. 🧠 Spaced Repetition That Works Saved words are reviewed 10 times over ~30 days on a scientifically-informed schedule. Reviews show the word in real-world sentences — not boring flashcards. Hit "Another Example" to see more context. 📖 Wikipedia Fallback Can't find "CBD" or "ADHD" in the dictionary? Dictionary Dad automatically checks Wikipedia for acronyms, brands, scientific terms, and more. 🔒 100% Private No accounts, no sign-ups, no analytics, no tracking.
