Cortana's features include being able to set reminders, recognize natural voice without the user having to input a predefined series of commands, and answer questions using information from Bing (like current weather and traffic conditions, sports scores, and biographies) .  Cortana also includes a music recognition service. Cortana can also roll dice and flip a coin by asking the commands "roll a dice" (one die), "roll the dice" (two dice), and "flip a coin",Concert Watch is a feature that helps Cortana determine which bands or musicians you are interested in . Cortana also integrates with the Microsoft Band for Windows Phone devices if connected via bluetooth. On the Microsoft Band Cortana can make reminders and bring phone notifications.

Since the Lumia Denim series, launched in October 2014, active listening was added to Cortana, enabling it to be triggered with the phrase: “Hey Cortana,” even across the room and without the need to touch the phone. After the trigger phrase is spoken, Cortana can be controlled normally for tasks like setting a reminder, asking a question, or launching an app.

Cortana also integrates with services like Foursquare to provide restaurant and local attraction recommendations.

Her Functions

The "Notebook" is where personal information such as interests, location data, reminders, and contacts will be stored for access by Cortana. Cortana will be able to draw upon and add to this data in order to learn the user's specific patterns and behaviors. The user will be able to view this information, with the aim of offering greater control over privacy settings by allowing them to specify what information is collected, "a level of control that goes beyond comparable assistants".Users can also delete information from the "Notebook" if they deem it undesirable for Cortana to know.

Most versions of Cortana take the form of two nested, animated circles. The circles are animated to indicate certain activities such as searching or talking. 

Cortana features a "do-not-disturb" mode in which users can specify "quiet hours", something that is already available for Windows Phone 8.1 users. Users can change the settings so that Cortana calls users by their names (or nicknames) .

Cortana correctly predicted the winners of the first 14 matches of the 2014 FIFA World Cup knockout stage, including the semi-finals, before it incorrectly picked Brazil over theNetherlands in the third place play-off match. This streak topped Paul the Octopus who correctly predicted all 7 of Germany's 2010 FIFA World Cup matches as well as the Final. Furthermore Cortana can also predict the games of various other sports such as the NBA, the NFL,the Super Bowl, the ICC Cricket world cup and various European Football Leagues. Cortana can also solve mathematical equations, convert units such as between Celsius and Fahrenheit, meters and feet, and calculate the exchange rate between currencies including Bitcoin.
