Looks like the Cortana team is putting the final touches on their Uber integration. Starting today some users, including ourselves, noticed that under Cortana's Notebook > Connected Accounts an option for the call-up car service has appeared. The ability appears only to be for those using Insider releases of Windows 10 and not build 10240.
Unfortunately, once you begin the process of linking Cortana to Uber, it appears to fail. This issue is likely due to something on Uber's end as the coordinated effort goes forward.
The option for Connected Uber accounts also appears under Cortana in Windows 10 Mobile. However, it refers you back to the PC for further setup.
Microsoft announced their Cortana-Uber integration back in May during Build. From the announcement:
"Universal Windows apps integrate with Cortana through the Voice Command Definition extensibility API. When integrating with Cortana, an application can choose to get launched or choose to interact with customers through Cortana's user interface canvas. Immaterial of the actual method an app chooses to integrate with Cortana, she will always preserve and provide all context she has about the specific task at hand."
Microsoft offered an example of how the Uber driver app for Windows 10 will use Cortana:
"By integrating with Uber, Cortana will not only recommend a Uber for you at the exact time you need it based on your schedule but will also order it for you. For example, let's say you've purchased a movie ticket online and received an email confirmation. Cortana has this information and will display a reminder to you prior to the movie start time. Along with that reminder, Cortana will also give you the option to get a ride with Uber. If you choose Uber, Cortana will automatically fill in the pick-up and drop-off details and request you a ride. You have the option of editing the pick-up and drop-off location. Finally, track the location of your Uber, all from within Cortana.
Uber is but one example of Cortana integration that is coming. Beginning last week, some users were able to connect up LinkedIn to Cortana and more services like Viber and Shopular are expected to come to the personal digital assistant.
