At an event unveiling the upcoming Windows Phone 8.1 update, Microsoft finally took the wraps off Cortana, the company's answer to Siri and Google Now.
Named after the artificial intelligence character in the “Halo” games, the voice-controlled digital assistant is powered by Microsoft’s Bing search engine and will replace the search button in Windows Phone software. Cortana can be used to make phone calls, send text messages, set quiet hours, take notes and give reminders.
The feature will launch in beta in the U.S. and will expand to other markets later.

In his keynote announcement at the annual Microsoft Build developer conference Wednesday, Windows Phone Corporate Vice President Joe Belfiore said Cortana can also be taught users' interests, relationships, frequent calendar events, family and much more through the use of her “Notebook” function.
Gizmodo reports that the Notebook stores anything users specifically teach the female-voiced personal assistant, as well as contextual information she picks up on her own, like frequently called numbers, favorite locations and common search queries.
For those who are turned off by the idea of their phone learning too much about them, the Notebook can be customized. Users can make certain people and topics off-limits to Cortana’s reach. In other words, users have a measure of control over what information the assistant can and cannot access.
“Windows Phone 8.1 is going to start rolling out to consumers as an update in the next few months,” Belfiore said. He later explained that the system will be available on new Windows Phones sometime later in April.
