Google Now is an intelligent personal assistant feature available for the Google Android and Apple iOS platforms. As with Apple’s Siri voice assistant, Google Now can answer queries and perform actions via voice commands using a natural language user interface.
The real power of Google Now is that it additionally relies on a user’s preferences and search history to anticipate future needs and deliver personalized information based on those needs before the user asks for it.
Google introduced Google Now in July 2012, and the feature is currently available for free as part of the Google Search app for Android and Apple iOS devices.
