Atua

Atua is a macOS utility that runs AI models and system tools from any application using custom shortcuts, text selection, or voice input.

Atua enables users to run AI models and execute tasks without leaving their current application on macOS. Users trigger commands by selecting text, using hotkeys, or dictating via voice input. The software supports MCP servers to connect external tools like databases or APIs and can read or write to native system apps like Calendar, Reminders, and Notes. Commands can pull context from screenshots, the clipboard, and system data. The software requires users to bring their own API keys for AI models, allowing flexibility in model choice. It operates locally for privacy, with network requests limited to AI model calls.
