ChatGPT iMessage integration is now available on Mac, allowing OpenAI’s chatbot to read, search, summarise and send messages through Apple’s Messages app.The new plugin, launched this week for Macs running Apple silicon, expands ChatGPT’s ability to take real actions inside personal messaging. Users can ask the system to review recent conversations, draft replies, delete messages or send texts on their behalf.
OpenAI says the plugin runs locally on the user’s machine and does not create a full index of all messages. Sending messages requires explicit user approval by default. The company warns against enabling persistent approval, noting that doing so removes the final opportunity to review a message before it is sent.Activating the integration is deliberately multi-step. Users must grant ChatGPT access to on-device Messages history, Full Disk Access through macOS System Settings, contact names and automation permissions.
The setup process is designed so the feature cannot be enabled accidentally.The plugin is currently limited to certain ChatGPT accounts on Mac, with reports indicating availability first for Work and Codex users. It does not run on Intel-based Macs.
Apple was not involved in the announcement. The company has long positioned itself as a defender of user privacy and has previously taken steps to restrict unauthorised access to iMessage. In earlier cases involving third-party apps that interfaced with the messaging system, Apple moved to cut off access when it viewed the integration as unauthorised.OpenAI’s approach relies on standard macOS permissions that any application with sufficient privileges can request.
Because the Messages database resides on the local disk, an app granted the right permissions can read and interact with it without needing a special partnership with Apple.Privacy advocates and security researchers have noted the sensitivity of granting an AI system access to private conversations. Even with local processing claims, the ability to summarise contact patterns, draft replies in a user’s style and send messages introduces new vectors for both convenience and potential misuse.
OpenAI encourages users to monitor the system’s actions closely.The launch continues a broader industry trend of giving AI assistants deeper control over personal devices and applications. ChatGPT and competing systems already handle email, calendars, documents and web browsing in various forms. Messaging represents a particularly intimate data set.
For Apple, the development arrives amid ongoing competitive and regulatory tensions with OpenAI and other AI providers. Apple has been expanding its own on-device and private-cloud AI features while maintaining strict controls over how third parties interact with core services such as Messages, Siri and system-level data.Users who choose to enable the plugin gain the ability to offload routine messaging tasks, receive conversation summaries and have ChatGPT suggest or complete replies.
Those who decline retain the existing separation between the chatbot and their private message history.OpenAI has not detailed plans for bringing equivalent functionality to iPhones or iPads. On mobile devices, the permission model and sandboxing rules differ significantly from macOS, making a comparable integration more complex.
As AI systems move from answering questions to taking actions across personal apps, the balance between usefulness and data exposure continues to shift. The new Messages plugin illustrates both the technical possibility of deeper integration and the privacy trade-offs that accompany it.
