Frequently asked questions
Quick answers about this topic hub.
What's the difference between UX and UI?▾
UI (user interface) is how a product looks — the visual and interactive elements. UX (user experience) is how it works and feels across the whole journey. Good UI serves good UX; you need both, but UX defines whether the product truly helps people.
Why does user research matter?▾
Because you are not your user. Research — interviews, usability tests, and observing real behavior — reveals what people actually need and where they struggle, so you build the right thing instead of guessing.
