ChatGPT can now read your Mac’s Messages history, draft replies, and send texts through Apple’s Messages app. That sounds like an iPhone feature, but the biggest catch is where it actually works.
OpenAI’s Apple Messages plugin brings ChatGPT into real conversations on compatible Macs. It can search threads, summarize chats, find past details, draft responses, and send iMessage, SMS, or RCS messages after approval.
The integration could be especially useful for people who handle work conversations through Messages. Instead of scrolling through long threads or copying text into ChatGPT, users can ask the assistant to find context and prepare a response directly from the conversation.
What ChatGPT adds to Messages
The plugin changes ChatGPT from a writing tool into an assistant that can work with existing conversations. Users can search Messages by person, keyword, or topic, open relevant threads, and surface information buried in older exchanges.
That makes long group chats easier to manage. ChatGPT can summarize unread conversations, identify decisions, highlight action items, or find when someone mentioned a specific subject. It can also create replies based on surrounding conversation instead of relying on pasted text.
Drafting is another major part of the integration. A user can ask ChatGPT to prepare a response in a particular tone or create several messages. It can also turn a project update into a concise text. Once approved, the plugin can send it through Messages.
Sending comes with an important safeguard
ChatGPT does not simply decide to start texting people on its own. By default, it shows the proposed message and intended recipients before sending. That gives the user a final opportunity to check both details.
Users can remove that confirmation requirement for an individual conversation. OpenAI warns that this removes the final review before ChatGPT sends a message as the user. The default approval flow is therefore safer.
The plugin can also delete specific messages or clean up threads when asked. For power users, that opens possibilities such as removing promotional messages without having to manually search through Messages.
Who can actually use the plugin?
The biggest limitation is platform support. The Apple Messages plugin is available only in the ChatGPT desktop app for macOS, and it requires an Apple Silicon Mac. Intel-based Macs are excluded.
The feature is also limited to ChatGPT Work and Codex surfaces. It does not appear in ordinary ChatGPT chats, the web app, or mobile apps. It also excludes Codex CLI and integrated development environment extensions.
OpenAI says the plugin is available across ChatGPT plans on macOS. Work or Codex access can depend on account, workspace role, or administrator settings. iPhone-only users currently cannot use this integration.
What happens behind the scenes?
The plugin uses macOS automation technologies, including AppleScript and Accessibility APIs, to interact with Messages. It can open the app, navigate conversations, and trigger sending or deletion actions when instructed.
Message content is read from the Mac’s local Messages database rather than through a continuous cloud index. OpenAI says processing occurs locally on the Mac. Messages are not sent to its servers unless users explicitly save a conversation to the cloud.
The plugin also works on request rather than monitoring the inbox. A user must ask ChatGPT to search, summarize, draft, or send, limiting what the assistant does without explicit instruction.
Setting up the plugin requires permissions
Giving ChatGPT access to Messages is not a simple switch. The plugin requires Full Disk Access to files used by the Messages database, along with Contacts access to resolve recipients.
macOS also requires automation permissions that allow ChatGPT to control Messages via AppleScript and Accessibility. These permissions give the application substantially more control than a normal messaging utility would receive.
After installing the latest Apple Silicon ChatGPT desktop app, users can enable Apple Messages from the Plugins section. macOS then presents permission prompts, and each permission can be revoked later in System Settings.
Privacy deserves a closer look
The convenience comes with a significant trust decision. Full Disk Access and automation permissions give ChatGPT broad privileges on a Mac. That makes this more powerful than asking an AI chatbot to rewrite copied text.
The local-first design reduces some exposure because message content is not continuously indexed in the cloud by default. However, saving a conversation to the cloud brings ChatGPT’s data-handling and retention policies back into play.
Apple Intelligence takes a different approach
Apple already uses Apple Intelligence and Siri for message-related features, including summarization and smart replies. Apple’s approach emphasizes deep operating-system integration and on-device processing within its own ecosystem.
ChatGPT takes a more flexible approach. It can reason across longer conversation histories and locate specific details. It can also produce elaborate drafts and connect messaging tasks with Work or Codex workflows. The tradeoff is granting a third-party application broader system permissions.
Powerful workflows for everyday users
For professionals, the plugin could turn Messages into another place for task management. Users could ask it to summarize unread project conversations and draft replies for status requests, reducing repetitive inbox triage.
It can also help recover context. Prompts for finding the last mention of a Q4 roadmap can replace manual searches. ChatGPT can then draft a confirmation using that recovered context. Technical users could generate precise updates in Work or Codex and send them after review.
ChatGPT can remove selected promotional messages or clean up specific conversations when asked. That could make a cluttered Messages history easier to maintain.

TL;DR
- ChatGPT can now search, summarize, draft, send, and delete Messages content, making Apple’s messaging app more useful for AI-assisted communication.
- The Apple Messages plugin works only on Apple Silicon Macs through ChatGPT Work or Codex, leaving iPhone-only users without access.
- Sending remains user-controlled by default because ChatGPT displays recipients and draft content before completing each requested message for review.
- Full Disk Access, Contacts, and automation permissions make the integration powerful, but they also create important privacy and security considerations.
