The Siri app is said to let users interact with Siri via text and voice modes. The app will also let users see their previous chats, with Siri able to pick up where they left off. Making the Siri app function similarly to ChatGPT, Gemini, and Claude iOS apps.

"Extensions allow agents from installed apps to work with Siri, the Siri app and other features on your devices"

In Gurman's newsletter, he stated the App Store would have a dedicated "Extensions" section to install Siri extensions.

iOS 27 is also said to have a "major overhaul" when it comes to using Siri. According to Gurman, he says "Siri will have a redesigned interface, which may involve the Dynamic Island, and there will apparently be a systemwide 'Ask Siri' button in Apple's apps and a 'Write with Siri' button above the keyboard."
