After Microsoft vaguely confirmed last November that its digital assistant Cortana will be headed to other operating systems, the software giant is finally offering up specifics. Microsoft is now aiming to bring Cortana to iOS and Android devices as a standalone app, Reuters reports. What's more, the company is also looking to include technology from one of its artificial intelligence research projects, dubbed Einstein. "This kind of technology, which can read and understand email, will play a central role in the next roll out of Cortana, which we are working on now for the fall time frame," Eric Horvitz, managing director of Microsoft Research and a member of the Einstein project, told Reuters. We've already seen Cortana offer some basic digital assistant functionality on Windows Phones and Windows 10 -- it can tell you the weather, dictate messages, and remind you of appointments -- but it sounds like it'll soon get some deeper understanding of how we live and work.
