Macuse is a macOS-native AI assistant tool that connects AI clients (Claude, Cursor, Raycast, and any MCP-compatible client) to directly manage your calendar, email, notes, and control any Mac application — all on-device and private.
What is Macuse?
Macuse is a local AI integration layer for macOS that takes natural-language commands from your AI assistant and translates them into actions within native macOS apps (Calendar, Mail, Notes, Reminders, Contacts) and any third-party application via Computer Use. It runs as a background process on your Mac, requires only the permissions you approve (Calendar, Reminders, Contacts, Full Disk Access for Mail/Notes, Accessibility for Computer Use), and is available for download at macuse.app. The product is developed by Macuse (no corporate name stated on the page).

How does Macuse work?
After downloading and installing, Macuse auto-detects your installed AI tools (Claude Desktop, Cursor, Raycast, etc.) and configures everything with one click — no terminal commands or config file editing. You approve the permissions needed for each feature (Calendar, Reminders, Contacts, Full Disk Access, Accessibility), and the app runs as a background service. Your AI assistant sends commands through the MCP protocol to Macuse, which then performs the equivalent actions directly in the corresponding macOS application.
