Frequently Asked Questions
What’s the difference between UX and UI?
UX is the overall experience and strategy around a product, whereas UI is the set of visual and interactive elements that implement that strategy.

Which should I prioritize when launching a new product?
Start with UX to define goals, user personas, and journeys, then build the UI to materialise those insights with compelling visuals.
