The Cortana open beta for Android is now available, but you’ll need to be a United States resident to download it from the Play Store. Microsoft did state that it plans to bring its personal voice assistant to other markets, but did not list when Canada would be on that list.
The version of Cortana that is available on Android is a lot like her counterpart on Windows 10 PC and Windows Phone, but does lack the “Hey Cortana” voice feature as Android does not allow an app to continually access a device’s microphone. As this is a beta, Microsoft says that it is looking to employ user feedback to improve the app. Among other things, Cortana allows a user to set reminders, search the web, and track flight details.
Those keen on really keen on trying out Microsoft’s personal assistant can download the app APK from APK Mirror.
