Snapify is a handy little Chrome extension that I've shown to live audiences twice in the last two days. Both times I showed how it works I heard some "oohs and ahs." Snapify allows you to highlight any word or phrase on a webpage and quickly find definitions, videos, Tweets, and webpages about that word or phrase. See it in action in the video below.
Applications for Education
Snapify could be a great little tool for students to use when they're reading articles online. Anytime students come to a word or phrase that they don't understand they can simply highlight it and click "snap it" to find definition or explanation.
