Cortana is a personal assistant that made its first appearance on Windows Phone 8. It has been integrated to Windows 10 (replacing Bing Search) and will soon be made available for the Xbox One console and Android devices (app).
Cortana's natural language user interface allows users to ask their questions using a natural language. You can, for example ask Cortana for weather information, the latest scores of your favorite sports teams, traffic info... and it will fetch the information online (Bing SmartSearch).
Cortana also allows you to interact with your device using voice commands, set reminders, send emails and much more.
