How to Build Apps & Websites with AI A Practical Guide to Vibe Coding

Building apps or websites used to require coding skills, a developer team, and weeks (or months) of work. Not anymore. Thanks to generative AI, you can now turn your ideas into real, functional products with just a few smart prompts. In this class, I’ll show you how I build with Hostinger Horizons, an AI-powered app and website builder. But you’re free to use any platform you prefer — the focus here is on the workflow, not the tool itself.

Together, we’ll:

Use AI to generate app layouts and functionality step by step
Build and refine a real project: a simple Invoice Manager for freelancers
Integrate user authentication and databases with Supabase
Iterate on design, layout, and logic by “chatting” with the AI

This approach is called “vibe coding” — a relaxed, creative workflow where you explain what you want, refine the results, and quickly launch something real.

By the end of this class, you’ll know how to take an idea and transform it into a working app, without writing a single line of code. Whether you’re a freelancer, entrepreneur, or just curious about AI development, this course will show you how accessible app building has become.
