Summary
This tweet highlights a significant technical project by @micLivs, who reverse-engineered the generative UI system used in Anthropic's Claude. The implementation involves extracting a complete design system from conversation exports and utilizing morphdom DOM diffing to live-stream HTML content directly into native macOS windows. The project includes both a detailed technical article and an open-source repository, providing a blueprint for building high-performance, AI-driven user interfaces.
