Simon Willison recently demonstrated the power of "vibe coding"—a workflow where developers describe their vision to an AI and iterate based on the output—to create a bespoke macOS presentation app in under an hour. By leveraging AI assistants, Willison bypassed his lack of experience with the Swift programming language to build "Present," a lightweight tool designed to transform a series of URLs into a stable, full-screen presentation environment. This project addresses a niche but vital problem: the fear of a browser crash during high-stakes talks presented via web tabs.

The app includes sophisticated features like a built-in web server that acts as a remote control. By connecting a smartphone to the laptop via a secure network, a speaker can trigger slide transitions and even scroll through long web pages directly from their phone. This illustrates how modern AI tools allow engineers to focus on high-level architecture and specific utility rather than getting bogged down in the syntax of unfamiliar frameworks or languages.

A key takeaway is the "Linear Walkthrough" method, where Willison used the AI to explain its own generated codebase step-by-step. This approach maintains human oversight, ensuring that even AI-generated apps are fully understood by their human creators. For students, this signifies a future where the ability to articulate a technical problem and audit results is just as valuable as manual syntax knowledge.
