# System and in-app search

Make your app’s actions available to Apple Intelligence and Siri by adopting schemas for in-app search and content access.

## Discussion

The `.system` domain defines app schemas that provide a
structured representation for common search actions and content.
Apply schemas in the `.system` domain to make your app’s search and content access available to Apple Intelligence and Siri.

Unlike other domains that target a specific app category, the `.system` domain applies broadly.
Any app that enables searching or opening content can adopt these schemas.

- [`search`](/documentation/AppIntents/AppSchema/SystemIntent/search):
  An intent that searches in your app when people say phrases like “Find bicycle.” or “Search for mountains.”
- [`open`](/documentation/AppIntents/AppSchema/SystemIntent/open):
  An intent that opens content in your app when people say phrases like “Open my screenshot.png file.”

> Tip: Xcode generates a template implementation when you type `system_` and select a schema from the suggestions list.

For more information about making your app’s actions available to Apple Intelligence and Siri, see [Apple Intelligence and Siri AI](/documentation/AppIntents/apple-intelligence-and-siri-ai).
