Siri AI Apps
Domains, features, Search, and indexing
Features describe where an app integrates with the system. Domains describe the meaning of its actions and content. Neither is an App Store category.
Direct answer
What is a Siri domain?
A domain is a collection of Apple-defined schemas for a category of functionality. An app maps its own intents, entities, and enumerations to those schemas so Apple Intelligence and Siri can understand them consistently.
How the pieces fit together
Feature
Start with the confirmed system experience: Siri AI, Shortcuts, App Shortcuts, Spotlight indexing, Assistant, or Visual Intelligence.
Domain
Then identify the schema family, such as Calendar, Notes, Photos, Reminders, or a Shortcuts-specific domain.
App Store category
Keep Apple’s merchandising category separate. A Productivity app may support several features and schema domains.
Features
Features are the directory’s top-level filter. Shortcuts support is separate from App Shortcuts, and neither implies Siri AI support.
Siri AI
Confirmed integration with Apple Intelligence and Siri AI.
127 confirmed appsShortcuts
Confirmed actions or automation support in the Shortcuts app.
62 confirmed appsApp Shortcuts
Developer-confirmed preconfigured App Shortcuts, recorded separately from broader Shortcuts support.
43 confirmed appsSpotlight indexing
App Entities donated to Spotlight for lexical or semantic discovery.
44 confirmed appsVisual Intelligence
Returning app results for content recognized through Visual Intelligence.
9 confirmed apps
Apple documents Assistant and Visual Intelligence as single-purpose schema domains. Because they connect to specific system surfaces outside Siri, this directory presents them under Features rather than under Siri domains.
Primary Siri domains
Apple groups common actions and content into category-specific primary domains. Apps can adopt more than one domain, but each schema should genuinely match what the app does.
Audio
Audio playback actions and media content.
4 confirmed appsCalendar
Creating, finding, updating, and managing calendar events.
6 confirmed appsCamera
Capturing photos and video with camera apps.
1 confirmed appClock
Creating and managing alarms and timers.
3 confirmed appsFiles
Opening and managing files and folders.
2 confirmed appsMail
Creating, finding, and managing email.
0 confirmed appsMaps
Searching places, directions, and navigation.
4 confirmed appsMessages
Sending and managing messages and conversations.
0 confirmed appsNotes
Creating and updating notes.
9 confirmed appsPhone
Starting and managing calls.
0 confirmed appsPhotos
Finding, opening, editing, and managing photos and video.
2 confirmed appsReminders
Creating and managing reminders and task-like items.

The key fallback
System and in-app search
Apple’s System domain provides schemas for searching and opening content. Unlike category-specific domains, it applies broadly to any app that can search or open content.
We call it the Search fallback: if an app doesn’t fit Calendar, Notes, Photos, Reminders, or another primary category, Search may still give Siri a structured way to invoke the app’s search experience. It can also be adopted alongside another domain. “Fallback” is our editorial shorthand, not a claim that the system adds it automatically.

Spotlight indexing
An indexed app includes its App Entities in a Spotlight index. That makes the app’s content findable through Spotlight’s lexical and semantic search, and Apple says indexed content can also support experiences such as Siri and Apple Intelligence.
Search and indexing are not interchangeable. Search exposes an action that performs or opens search in the app. Indexing exposes individual app content to Spotlight. An app may support either one or both.
The directory only applies the Spotlight indexing feature when a developer confirms App Entity indexing.

These schemas work with the Shortcuts app, but Apple says they don’t make conforming types discoverable by Apple Intelligence and Siri. They remain domains—not feature labels. We keep them separate from Siri domains and from the broader Shortcuts and App Shortcuts feature labels.
