User experience (UX) design is the process of creating products, services, and experiences that meet the needs of users. UX design focuses on providing a user-friendly interface and making sure that users find the product or service satisfying and enjoyable to use.

User interface (UI) design, on the other hand, is the process of designing the visual aspects of products and services. UI design focuses on how the interactivity of a product looks and feels, and how its screens, displays, and controls interact with users.

UX and UI design have different goals. UX design aims to provide a positive user experience, while UI design focuses on the aesthetical aspects of a product. UX design requires an understanding of the user’s needs, motivations, desired outcomes, and reactions to changes. UI design requires an understanding of user interface design principles such as color, typography, layout, navigation, and how to craft an aesthetically pleasing user interface.

The two disciplines do share some similarities, such as the need to make products or services appealing to the user. However, their goals and processes are different. UX design requires an understanding of human behavior and how to make a product or service intuitive and user-friendly, while UI design requires an understanding of design principles and the ability to create visually appealing interfaces.
