Features Overview
Macuse gives AI assistants two complementary ways to interact with your Mac:
App Integrations
Native, structured access to Calendar, Mail, Notes, Reminders, Messages, Contacts, Stickies, Maps, and Location.
Computer Use
See and control any Mac app, even ones without a dedicated integration. Computer Use for any AI client, running on-device.
When to use which
App Integrations are the default. They use the app's own data store (CalDAV, Mail.app's database, Notes' SQLite, etc.) instead of clicking around the UI. They're faster, more reliable, and read structured data. Emails come back as objects, not screenshots.
Computer Use fills the gap. Whenever an app has no integration (a browser, a third-party design tool, an internal enterprise app), Computer Use lets your AI drive it the same way a human would: clicking, typing, navigating menus. It runs in the background so your active window and cursor stay untouched.
Most prompts are answered by an integration. Only fall back to Computer Use when the app you need is not covered by one of the integrations above.
