Virtual assistants are capable of a wide range of functions, such as scheduling appointments, sending messages, making phone calls, setting reminders, providing weather updates, searching the internet for information, playing music, and controlling smart home devices. They can also integrate with other applications and services to streamline workflows and enhance productivity.
