I have made many such ai web apps and won hackathon too in which I made a website which uses ai which works like a therapist

I’d approach designing a web app by putting usability first while letting aesthetics enhance it, not compete with it. That starts with understanding the target audience—their needs, pain points, and the tasks they care about most—then creating a clear, intuitive layout where navigation feels natural and important actions are easy to find. I’d keep accessibility in mind from the start with proper contrast, readable fonts, and keyboard-friendly design so it works for everyone. For aesthetics, I’d use clean visuals, balanced spacing, and a strong visual hierarchy so the design looks appealing but also guides the user’s attention. Finally, I’d iterate based on real user feedback, refining until the app feels effortless to use and pleasant to look at.
