Microsoft Cortana

Microsoft Cortana is a virtual assistant developed by Microsoft. It uses artificial intelligence to help users with various tasks, such as setting reminders, answering questions, managing schedules, and controlling smart home devices. Initially integrated into Windows operating systems, Cortana can also work across other devices and platforms. It learns from user interactions to improve its functionality over time. While it started as a competitor to other assistants like Siri and Google Assistant, Microsoft's focus has shifted towards enhancing productivity features within applications like Microsoft 365.
