Highlight Define

Highlight a word. Understand it instantly. Highlight Define shows a small card right next to any word or phrase you highlight, with: - Definitions: part of speech, clear meanings, and example sentences - A plain-language explanation of the topic from Wikipedia, for concepts a dictionary doesn't cover ("supply and demand", "mitochondria", "Treaty of Versailles") - Images: photos and diagrams from Wikimedia Commons that show what the word actually looks like - Pronunciation audio when it's available Built for reading: textbooks, articles, research papers, class notes. No more opening a new tab, searching, and losing your place. WORKS IN GOOGLE DOCS Highlight a word in a Google Doc and the card appears there too. YOUR CHOICE OF HOW IT OPENS Click the toolbar icon to choose: - Show the card right away - Show a small "?" button first - Only when you hold Alt/Option while highlighting PRIVATE BY DESIGN - No account, no sign-up, no ads, no tracking - Only the text you highlight is sent, and only to public reference services (Wiktionary, Wikipedia, Wikimedia Commons, Free Dictionary API) to fetch results - Nothing is stored or sold Press Esc or click anywhere to close the card. Note: Google Docs support relies on how Docs currently works and may briefly stop working if Google changes Docs. The extension still works on regular websites.
