Key Features and Benefits
A recent update revolutionized ChatGPT’s voice mode by integrating it into the main chat window instead of a separate interface. Responses now appear in real-time, combining spoken output with on-screen text and generated visuals, maintaining conversation context seamlessly while allowing smooth transitions between typing and speaking.
The Dynamic Island integration enables multitasking during voice sessions. When you swipe away from ChatGPT, conversations continue in the background with the assistant’s status displayed in the Dynamic Island. Simply tap the island to return to the app, or tap “End” to stop the session.
Important Limitations to Know
While this setup provides quick physical access to a more context-aware assistant, ChatGPT cannot perform Siri-like system actions such as accessing your calendar, setting alarms, controlling HomeKit devices, or launching apps. It functions purely as a conversational AI assistant without deep iOS integration.
Apple currently doesn’t allow users to replace the Side button’s Siri functionality with alternative assistants, making the Action button assignment the only native workaround for quick AI assistant access on newer iPhone Pro models.
