Cortana

Cortana is a virtual assistant created by Microsoft, designed to help users perform tasks using voice commands or typed requests. It can answer questions, set reminders, manage calendars, and control smart devices, among other functions. Cortana learns from user interactions, allowing it to provide personalized responses and suggestions. Initially launched as part of Windows Phone, it has since been integrated into Windows operating systems and other Microsoft products, making it easier for people to access information and manage their daily activities through natural language processing.
