The battle for personal assistand domination is well underway with yesterday's announcement of Google Home, hints that Siri will be coming to OS X, and now with Microsoft's Cortana assistant crossing over to the Android realm via an app but currently only for the US.
Cortana manages your schedule, your interests, your people, your reminders—Cortana makes sure all that stuff is available wherever you need it. You can set a reminder to pick up milk on the way home while you’re on your PC at work, and Cortana will give you the heads up on your phone when you’re on the road. You can also ask Cortana to make an appointment, send an email, open an app, or help you find what you’re looking for. And it’s not only about productivity, Cortana’s always up for a little chit chat. She's also pretty savvy about predicting outcomes of sports matches.
Powered by Bing, the Cortana version for Android requires your companion PC to be running version 1511 or later. Canadians who really want to use the app have to likely change location on their devices which may not be ideal for other apps.
