[2][3] Voice interaction with Cortana provides features such as setting alarms, facts, searches, weather, news, traffic, flights, and other real-time information.

Additionally, the speaker's Cortana integration with one's Microsoft Account enabled calendars, reminders, commutes, to-do lists, and home automation features, among others.

The Invoke also had access to Cortana Skills Kit which enabled features such as home automation, music streaming, and other mobile app integration.
