Apple's new Siri app enhances the assistant for longer conversations, letting users revisit responses, continue chats across devices, and pin exchanges for later use. Voice activation via 'Hey Siri' remains better for quick tasks like timers, reminders, music, directions, and smart home controls. Siri AI has been in developer testing since June 8 on iOS 27, iPadOS 27, macOS 27 Golden Gate, and visionOS 27, with watchOS 27 testing planned for a future beta and an English-language user beta expected later in 2026.

The Siri app uses iCloud to privately sync conversational history across supported devices, allowing users to start a conversation on a Mac and continue it on an iPhone or iPad. Compatible hardware includes iPhone 15 Pro and Pro Max, all iPhone 16 models and later, iPad mini with A17 Pro, iPad models with M1 or later, MacBook Neo with A18 Pro, Mac models with M1 or later, Apple Vision Pro with M2 or later, Apple Watch Series 9 or later, Apple Watch Ultra 2 or later, and Apple Watch SE 3. Apple Watch requires a nearby Apple Intelligence-enabled iPhone.

The initial user beta will require a supported device set to English. Siri AI will not initially be available on iPhone, iPad, or Apple Watch in the European Union, though supported Mac and Apple Vision Pro users there will have access in supported languages. Apple Intelligence remains unavailable in mainland China, despite regulatory clearance.
