Microsoft's personal assistant Cortana is coming to Android and iOS.
Microsoft is working on an advanced version of its competitor to Apple's Siri, using research from an artificial intelligence project called "Einstein.", Reuters reports.
Microsoft has been running Cortana on its Windows phones for a year, and will put the new version on the desktop with the arrival of Windows 10. Later, Cortana will be available as a standalone app, usable on phones and tablets powered by Apple iOS and Google's Android.
