What features are available to developers in Apple Intelligence?

Apple Intelligence, introduced at WWDC 2024, offers several features for developers:

1. Device Semantic Index: This organizes personal information from across apps, allowing Apple Intelligence to ground requests in relevant personal context.

2. App Intents Toolbox: This understands app capabilities and can take actions on behalf of the user. Developers can expose their app's capabilities to Apple Intelligence for deeper integration into system experiences.

3. Generative AI Models: Apple Intelligence uses powerful generative models for understanding and generating language and images, helping users take actions with awareness of personal context. These models are designed to run on-device for low latency and privacy.

4. Writing Tools: These tools help users communicate more effectively by rewriting text for tone and clarity, proofreading, and summarizing key points. They integrate seamlessly with system text and web views.

5. Image Playground API: This allows developers to integrate image creation features into their apps without needing to train models.

6. Siri Integration: Apple Intelligence enables Siri to access app data and capabilities more naturally. Developers can use app intents to integrate with Siri and the Shortcuts app.

These features are designed with privacy and security in mind, leveraging Apple's on-device intelligence stack and private cloud compute. For more details, you can refer to the Platforms State of the Union (01:35) session.
