Smarty Synonym

Double-click any word for synonyms, antonyms, meaning, pronunciation & origin. Light/Dark themes and per-feature toggles.

Smarty Synonym turns any word on any webpage into an instant lookup. Double-click a word, right-click and choose "Find Synonyms," or just select text and tap the floating icon that appears, a small popup shows you everything you need without leaving the page. What's new in v2.3: 🎨 Real theme control. Choose Auto, Light, or Dark yourself instead of only following your system setting — switches instantly, everywhere the popup appears. 🎛️ Turn any feature on or off. Antonyms, Meaning, Pronunciation, Word origin, and the Undo toast are now individual switches, not all-or-nothing, keep only what you use. 🔍 A floating icon now appears when you select text, so you don't have to remember double-click or right-click to trigger a lookup. 📚 Richer definitions. The meaning popup now shows up to three parts of speech (e.g. "run" as a verb and a noun) instead of just the first definition it finds. ✍️ Phrase support. Select a short phrase like "look up" or "set off" and get its synonyms, not just the first word. ✅ Better spelling recovery. Misspelled words now fall back to a live suggestion lookup instead of only checking a small built-in list. What you get, in one click: ✨ Synonyms & Antonyms. Switch between tabs to find a better word or its exact opposite. 💡 Instant Meaning. Tap the meaning icon for a quick definition, no extra tab or lookup needed. 📖 Word Origin. Curious where a word comes from? The origin icon pulls its history straight from Wiktionary. ✅ One-Click Replace. Click any suggestion and it swaps directly into the text you're editing or reading. ↺ Undo Anytime. Changed your mind? A floating Undo button stays available even after the popup closes. ⚡ Three Ways to Trigger. Double-click, right-click, or select text and use the floating icon — turn any of them off from the toolbar popup.
