AI tools like Cursor, Claude Code, and Lovable have made it possible for anyone to build web applications — but most people are doing it blindly. They accept whatever the AI generates and end up with projects they can't explain, debug, or extend. This course gives you the foundational knowledge to vibe code with understanding. You'll learn the landscape of AI building tools and how to choose the right one, the programming languages and tech stacks that power modern web apps, core concepts like databases, APIs, and authentication, and how to use AI to plan your application before building it. Built for non-technical builders — founders, creators, designers — who want to build with AI tools without being entirely dependent on them. No coding experience required. Not for experienced developers looking to add AI to an existing workflow. This is Course 1 in a multi-part series. Future courses cover building, security, and deployment.
