Catglish - Learn English as you read the web

Explains any word you click as you read English online, underlines the words you've looked up, and translates whole sentences.

Catglish turns the English you already read into your vocabulary practice. Catglish currently supports English to Chinese only: definitions, sentence translations and phrase explanations are shown in Chinese. Turn on learning mode on an article and click any word to see its definition and pronunciation in place, without leaving the page. Select a sentence and Catglish translates it in the side panel; select a short phrase and it explains the phrase in context. Every word you look up goes into your word list. From then on, Catglish underlines it wherever it shows up again, on any page you read, and the underline fades the more often you look the word up. Mark a word as known and it stops being underlined. FEATURES • Click-to-define: dictionary definitions and pronunciation, right on the page • Underlines the words you have looked up, wherever they appear again • Sentence translation in the side panel, and phrase explanations in context • A word list that follows you across devices, with how often you looked each word up • Save pages to read later; see them on catglish.com • Reading stats: how much you read and look up each day • Paste-in reader on catglish.com for text that isn't on a web page • Keyboard shortcut: Ctrl+Shift+E (Cmd+Shift+E on Mac) opens Catglish PRIVACY Catglish only acts on a page when you turn it on for that page. The page address, title and full text are never sent to our servers. Only the individual words, the word you click, and the sentence you ask to translate leave your browser.
