Cortana on Windows mobile and Android is capable of capturing device notifications and sending them to a Windows 10 device.
the English version of Cortana on Windows devices is available to all users in the United States (American English), Canada (French/English), Australia, India, and the United Kingdom (British English).
Cortana can integrate with third-party apps on Windows 10 or directly through the service.
Starting in late 2016, Cortana integrated with Microsoft's Wunderlist service, allowing Cortana to add and act on reminders. It can be disabled; this will cause Windows search to search the Web as well as the local computer, but this can be turned off.
Users can view and specify what information is collected to allow some control over privacy, said to be "a level of control that goes beyond comparable assistants".
Cortana has a built in system of reminders which for example can be associated with a specific contact; it will then remind the user when in communication with that contact, possibly at a specific time or when the phone is in a specific location.
