Atua

Atua is a macOS desktop app that brings AI assistance to any application. It allows users to create custom AI commands triggered by a keyboard shortcut (⌥ Space) from anywhere on the Mac. Users can select text, capture screen context, or use voice input, and the app sends the prompt to an AI model of their choice. Commands can pull in live context like selected text, screenshots, clipboard, voice transcripts, window content, or screen OCR. Atua supports custom prompts with hotkeys, output modes, and can run commands in the background. It integrates with system tools (Calendar, Reminders, Notes, Finder, Shortcuts, Shell, HTTP) and MCP servers for external tools like GitHub, Postgres, Slack, and Filesystem. The app is privacy-focused: no accounts, no analytics, and data stays on the Mac. Users bring their own API key from supported providers (OpenAI, Anthropic, Groq, Mistral, DeepSeek, xAI, Perplexity, Together AI, Fireworks, Cerebras, DeepInfra, Hugging Face, Cohere, OpenRouter, LLM Gateway, Ollama, LM Studio, or any OpenAI-compatible endpoint). Atua is a one-time purchase with a 7-day money-back guarantee.
