Some screenshots that reportedly show the recently revealed Work Assistant app for Windows Phone in action have surfaced. The app, which first appeared in the Windows Phone Store in December, is currently an internal Microsoft project that is supposed to add Cortana voice integration features for Office users.
The screenshots are from WindowsBlogItalia and show how the app is supposed to work with Cortana to open, search, and share Office files.
Another screenshot offers some helpful tips on how to use the Work Assistant app. Since this is still supposed to be an internal Microsoft project, we won't likely get a release date for some time.
