Windows Phone 8.1 released today and of course one of the major features is Cortana the digital assistant. The feature that helps set Cortana apart from Siri and Google Now is the deep application integration. This deep application does not just launch the app but actually allows you to control different aspects of the app. To take advantage of this feature, first you need to figure our which apps she can work with. Here is a quick tip to determine which apps on your Windows Phone Cortana can work with.
Launch Cortana and in the middle of the screen hit see more option. Once the list comes up, scroll to the bottom to see all the installed apps that work with Cortana.
Click on any of the apps listed to see the commands that are supported.
I am not sure if that is a complete list but I suspect that it is. If you see another way to determine which apps work with Cortana let us know in the comments.
