Sky is an AI-powered assistant for macOS that acts as an intelligent overlay to help users control their Mac using natural language. Developed by the creators of Apple's Shortcuts app, it understands context across open apps and windows, enabling users to perform complex tasks with simple commands. Sky integrates with core macOS applications like Calendar, Messages, and Safari, and supports custom tools via scripts. Users can automate multi-step workflows (like summarizing articles and sharing them) without switching between apps, making it ideal for productivity enthusiasts and Mac power users looking to streamline their digital workflows.
