Satvik, founder of Build Fast with AI, introduced the concept of "Vibe coding" - using AI tools to build websites and applications with minimal human coding effort - demonstrating how to create everything from simple portfolio websites to complex project management tools using platforms like Plot AI, Gemini Canvas, and V0. He explained the three levels of no-code AI development and showcased how these tools are drastically changing software development by enabling one person to accomplish in a day what previously required multiple specialists working for months.
