On stage today, Microsoft and Amazon employees demonstrated how Cortana and Alexa can be used together. Asking Alexa to open Cortana gives users access to Microsoft's assistant through Alexa-enabled devices like the Echo. Similarly, by asking Cortana to open Alexa, Amazon's assistant becomes available on more devices, like a PC. With this feature, users with Amazon smart speakers can utilize Cortana's integration with Office Suite while those using Cortana-enabled devices can also take advantage of the tens of thousands of skills that come with Alexa.

Microsoft said that the digital assistant integration is currently only available in a limited beta but those interested can sign up here to receive an alert when it goes live.
