Looking for another word? Select it, right-click, and Synopedia shows its synonyms grouped by meaning, plus three antonyms. No new tab, no lost train of thought. ✍️ 🖱️ HOW IT WORKS 1. Select a word on any page (a double-click is enough). 2. Right-click and choose “Synonyms for …”. 3. Click a synonym: in a text box it replaces the word right away, capitals kept. Elsewhere it is copied, ready to paste. You can also click the toolbar icon and type a word. Suggestions appear from the first letters. 🧭 SYNONYMS BY MEANING The right synonym depends on the meaning, so Synopedia keeps the meanings apart: • say → utter, declare (speak) · assert, allege (claim) · presume, assume (suppose) • big → large, huge, massive · grown-up, adult · opposite small Labels such as informal, formal, slang or dated, and regional tags (US, UK, AU), tell you whether a word fits a cover letter or a text to a friend. 🎓 WHO IT’S FOR Students writing essays, job seekers polishing a résumé or cover letter, professionals sending emails, bloggers and copywriters, and anyone learning a language and building vocabulary. 🌍 SIX LANGUAGES English, French, Italian, Spanish, German and Catalan. The language comes from the page, and you can switch in one click. Spelling variants are recognized (colour → color). 🔒 OFFLINE AND PRIVATE The thesaurus is built into the extension, so it works without a connection. No data collected or sent, no account, no ads, no tracking. The page is read only when you choose “Synonyms for …”. 🛡️ PERMISSIONS Context menu (the right-click entry), active tab (the selected word, only after your click), scripting (replacing the word), storage (your language, on your device).
