ChatGPT on Mac Gains Ability to Read and Reply to iMessages

How the i Message Integration Functions in Practice

OpenAI has released a new plugin enabling ChatGPT on Mac to access and respond to Apple's Messages app. The feature is currently limited to users of ChatGPT Work and Codex subscriptions, allowing them to search through conversations and generate replies directly within the messaging interface. The rollout was announced recently and integrates the AI assistant into native macOS messaging functionality.

The plugin works by requesting permission to read and send messages through the Apple Messages app, after which ChatGPT can analyze conversation history and suggest or send responses. OpenAI states the tool is designed to help users manage communications more efficiently, particularly in professional settings where quick replies are valuable. However, as noted by Bloomberg, the integration has sparked discussion around data privacy, given that the AI gains access to personal message content.

Could This Raise Privacy Risks for Everyday Users?

Once activated, the plugin appears as an option within the Messages app on Mac, where users can invoke ChatGPT to summarize chats, draft replies, or retrieve specific information from past conversations. The AI operates under user-initiated commands, meaning it does not actively monitor messages in the background. OpenAI emphasizes that message data is not stored or used to train models unless explicitly permitted by the user under existing data policies. The feature requires macOS Sonoma or later and is not available on iOS devices at this time.

Security experts have pointed out that granting any AI access to message content introduces potential vulnerabilities, especially if the plugin is compromised or misused. While OpenAI claims the tool follows Apple’s privacy frameworks and requires explicit user consent for each session, critics argue that the convenience may lead users to overlook ongoing access permissions. The company says it has implemented end-to-end encryption protections where applicable and that no message content leaves the device without user action.

Is the plugin available to all ChatGPT users? No, it is currently restricted to subscribers of ChatGPT Work and Codex plans on Mac computers.
