Apple's First Foldable iPhone Duo Expected to Support "Lightweight UI", Apple Pencil Hover Triggers Siri AI
IT Home, September 17 — Source @itspdfu posted on X today (September 17), revealing that Apple is introducing an interaction method called "Lightweight UI" for Siri AI. The relevant code has already appeared in the Writing Tools feature of macOS 27, and iPadOS 27 also includes a system toggle to control this interface, though it remains off by default. IT Home has included the related demo video below: On the interface, the UI adopts a minimalist design to reduce visual distractions. In terms of functionality, the Siri icon can expand into an "Ask Siri" and operation suggestions panel. The design aims to reduce the cognitive load of the AI assistant.

On the interface, the UI adopts a minimalist design to reduce visual distractions. In terms of functionality, the Siri icon can expand into an "Ask Siri" and operation suggestions panel. The design aims to reduce the cognitive load of the AI assistant, allowing users to focus more on the task itself rather than interface operations.
According to the existing demo logic, iPad users can hover the pointer over selected text using a Magic Keyboard to bring up this lightweight tool. Notably, iPadOS also includes a call path triggered by Apple Pencil hover, meaning users may be able to operate Siri AI directly via the stylus without switching to the keyboard or opening the full menu.
iOS 27 RC code has added an interface branch specifically for iPhone Duo, internally identified as "V68." Since this device does not primarily use a mouse and keyboard as input methods, it is speculated that Apple Pencil hover may become the key interaction method for triggering Lightweight UI on it.
If the report is accurate, iPhone Duo will not only gain stylus support but may also deeply integrate hover operations with Siri AI, text editing, and system suggestions.
