Imagine all of your actions being constantly monitored in order to build personalized search queries. Those last words you typed in a Word document or IM window. The e-mail you just sent. What words your cursor is next to. The text you copied to the clipboard. All of it constantly monitored and processed, in real-time, locally and/or using Google’s search engine in order to build search results for you in case you need them at a moment’s notice.
