PopUI

PopUI is a companion desktop app that creates a bi-directional bridge between Claude Desktop and visual interfaces. It enables Claude to create, display, and interact with user interfaces through a specialized MCP server, allowing both Claude and users to manipulate a shared visual context in real-time. The implementation leverages Electron to render React components dynamically, supports Tailwind CSS for styling, and includes features for sending messages back to Claude, making it particularly valuable for collaborative experiences like control panels, games, visualization tools, and other interactive interfaces where visual context enhances the conversation.
