Cortana by Microsoft

Cortana is Microsoft’s intelligent virtual assistant that aims to enhance productivity and simplify your digital life. Integrated into the Windows operating system, Cortana is designed to understand natural language and assist users in a variety of tasks such as setting reminders, sending emails, or finding files. While primarily known for its voice command capabilities, Cortana also offers text-based interactions for those who prefer not to speak.

The assistant is equipped with machine learning algorithms that allow it to learn from your behavior and preferences, thereby offering more personalized assistance over time. Although API access is limited, Cortana can still be integrated with certain Microsoft services and third-party applications, making it a versatile tool for both personal and professional use.
