I vibe coded my dream macOS presentation app (simonwillison.net)

At Social Science FOO Camp, a developer showcased a newly coded macOS presentation app called Present, created just hours before the talk titled “The State of LLMs, February 2026 edition.” The app enables presenters to display an ordered sequence of URLs in a streamlined interface, addressing the frustration of browser crashes during presentations. Built using Swift and SwiftUI, it offers automatic URL saving and a remote control feature via a mobile-friendly web server, allowing seamless client-server interaction without worrying about Wi-Fi limitations. This development is significant for the AI/ML community as it demonstrates the potential of rapid prototyping and "vibe coding" to address real-world needs with minimal resources. Present not only illustrates effective coding practices in Swift but also highlights the growing intersection of AI, software engineering, and user experience design. By solving a prevalent issue and showcasing the ease of creating functional apps, it empowers developers to pursue innovative solutions in their projects, even in unfamiliar programming environments.
