Leafy

Look up any word on your screen without leaving the page

You hit a word you don't know. Three tabs later, the paragraph is gone. Hold ⌥A, box the word, and Leafy answers for that sentence instead of the dictionary's first guess, over PDFs, ebooks, images, anything on screen. Every word saves itself, then comes back blanked out in the sentence you met it in. 10 languages.
