OpenAI has launched a new Apple Messages plugin for ChatGPT on Mac, allowing the AI assistant to read, search, summarize and draft messages stored in Apple’s Messages app. The integration can also send messages on a user’s behalf, bringing ChatGPT deeper into everyday communication workflows on macOS. The feature was rolled out on August 20, 2026, and is available across ChatGPT plans in the desktop app.
The new integration supports iMessage, SMS and RCS conversations and works within ChatGPT Work and Codex. However, it is not designed to let users interact with ChatGPT remotely through the Messages app itself. Instead, ChatGPT accesses the Messages database on the Mac and performs tasks through Apple’s Messages application. OpenAI says message sending requires user approval by default.
ChatGPT Can Now Work With Apple Messages
The Apple Messages plugin gives ChatGPT access to conversations stored in the Messages application on a Mac. Users can ask the AI to search through previous conversations, summarize long message threads, identify information and prepare replies.
For example, a user could ask ChatGPT to find a previous discussion about dinner plans, identify when someone is available, or summarize what was discussed in a particular conversation.
The integration is designed to eliminate the need to manually copy and paste message content into ChatGPT.
Key Features
| Feature | What ChatGPT Can Do |
|---|---|
| Search messages | Find information in previous conversations |
| Read conversations | Analyze relevant message threads |
| Summarize | Condense long conversations |
| Draft replies | Prepare responses based on context |
| Send messages | Send approved messages through Messages |
| Supported messaging | iMessage, SMS and RCS |
| ChatGPT Work | Supported |
| Codex | Supported |
| Regular ChatGPT chats | Not supported for this plugin |
The ability to work directly with existing message history is the biggest difference between the new plugin and simply asking ChatGPT to write a message from scratch.
How the Apple Messages Plugin Works
The plugin operates through the ChatGPT desktop environment on macOS rather than turning Messages into a ChatGPT chatbot.
Users install or enable the Apple Messages plugin and provide the necessary permissions. Once connected, ChatGPT can interact with eligible conversations stored on the Mac.
The integration can then be used for tasks such as searching old conversations, preparing replies and retrieving information from message history.
Example Tasks
| Task | Possible ChatGPT Action |
|---|---|
| Find an old message | Search conversation history |
| Summarize a group chat | Generate a concise summary |
| Reply to someone | Draft a response |
| Check previous plans | Search earlier messages |
| Find a birthday | Locate relevant information |
| Identify follow-ups | Suggest actions based on conversations |
| Send a response | Send after user approval |
This makes ChatGPT more like a desktop assistant that can work across a user’s existing communication data rather than a standalone text-generation tool.
Messages Integration Supports iMessage, SMS and RCS
The plugin is not limited to iMessage.
OpenAI’s integration supports three major message formats available through Apple’s Messages ecosystem: iMessage, SMS and RCS.
That means users can potentially search and work with conversations regardless of which supported messaging protocol was used.
Supported Message Types
| Message Type | Supported |
|---|---|
| iMessage | Yes |
| SMS | Yes |
| RCS | Yes |
| Other messaging apps | No, not through this plugin |
The integration is therefore focused specifically on Apple’s Messages application rather than providing a universal messaging assistant across every messaging platform.
Sending Messages Requires Approval
One of the most important safeguards is that ChatGPT does not automatically send messages by default.
When a user asks ChatGPT to send something, the system requires approval of the message and its recipients before sending it. Users can optionally enable persistent approval, but OpenAI warns that doing so removes the final review step before messages are sent.
Message-Sending Controls
| Action | Default Setting |
|---|---|
| Read messages | Requires permission |
| Search conversations | Requires permission |
| Draft messages | Allowed after setup |
| Send message | User approval required |
| Recipient confirmation | User approval required |
| Persistent approval | Optional but carries additional risk |
This is particularly important because a messaging assistant has access to sensitive conversations and can potentially communicate with other people on a user’s behalf.
Privacy Becomes a Major Issue
The new capability also raises privacy questions because ChatGPT can access personal message history stored on a Mac.
OpenAI says the plugin runs locally and does not build an index of all messages. However, the integration requires users to grant significant system permissions, including Full Disk Access, along with access related to contacts and automation.
That makes the permissions users grant during setup an important part of the security model.
Permissions and Privacy
| Area | Requirement/Information |
|---|---|
| Messages access | Required for message-related tasks |
| Full Disk Access | Required |
| Contacts | Permission may be required |
| Automation | Permission required for relevant actions |
| Message indexing | OpenAI says it does not build an index of all messages |
| Sending | Approval required by default |
Users should therefore understand what permissions they are granting before enabling the integration.
Apple Silicon Macs Are Required
The new Messages functionality currently works only on Macs powered by Apple Silicon processors. Intel-based Macs are not supported for the plugin at this stage.
That means users need a Mac with an M-series chip to use the feature.
Compatibility
| Requirement | Status |
|---|---|
| macOS ChatGPT app | Required |
| Apple Silicon Mac | Required |
| Intel Mac | Not supported |
| iMessage | Supported |
| SMS | Supported |
| RCS | Supported |
| ChatGPT Work | Supported |
| Codex | Supported |
OpenAI’s current macOS desktop application supports both Apple Silicon and Intel Macs generally, but the new Apple Messages plugin has the more restrictive Apple Silicon requirement.
ChatGPT Work and Codex Get the Integration
The Messages plugin is not limited to personal ChatGPT workflows.
OpenAI says it also works inside ChatGPT Work and Codex, allowing message-related tasks to become part of professional workflows.
This could make the feature particularly useful for people who manage communications while working on a Mac.
For example, an AI assistant could potentially search a previous conversation for project details, identify follow-up tasks or prepare a response while the user is working in another application.
However, workplace users need to pay particular attention to organizational policies because messages can contain confidential customer, employee or business information.
ChatGPT Is Moving Beyond the Chat Window
The Messages plugin is part of a broader trend in ChatGPT’s development: giving the AI access to applications and tools that users already rely on.
OpenAI’s plugin system is designed to package workflow capabilities and connect ChatGPT or Codex with external systems. The company’s current plugin directory allows users to review capabilities, permissions and connection requirements before enabling integrations.
The Messages integration takes this approach into one of the most personal areas of a computer: private communication.
From Chatbot to Desktop Assistant
| Traditional ChatGPT | New Messages Integration |
|---|---|
| User provides message text | ChatGPT can search existing messages |
| Generates standalone responses | Can draft using conversation context |
| User manually copies content | Plugin accesses supported conversations |
| Cannot send directly | Can send through Messages |
| Primarily conversational | More workflow-oriented |
This represents a broader shift toward AI systems that can perform actions rather than simply answer questions.
The Feature Could Save Time
For users with years of message history, searching through conversations manually can be time-consuming.
ChatGPT could make it easier to locate specific details that are buried in old conversations.
A user might, for example, ask the assistant to find when a friend previously said they were available, locate an address mentioned several months ago or summarize a lengthy group conversation.
The value comes from combining natural-language queries with access to existing message history.
There Are Risks With AI-Generated Replies
The ability to send messages introduces a different category of risk.
A generated response can misunderstand context, use an inappropriate tone or accidentally disclose information that should not be shared.
This is why OpenAI’s default approval requirement is important. Users can inspect the proposed message and recipients before anything is sent.
The risk becomes greater when persistent approval is enabled because the final human review can disappear.
Potential Risks
| Risk | Example |
|---|---|
| Wrong recipient | Message sent to the wrong contact |
| Incorrect context | AI misunderstands a conversation |
| Tone problems | Response sounds inappropriate |
| Sensitive information | Private information included accidentally |
| Automation error | Unintended message sent |
| Permission exposure | Excessive system access granted |
For these reasons, users should treat automated messaging as an action requiring oversight rather than simply another text-generation feature.
OpenAI’s Move Puts It Deeper Into Apple’s Ecosystem
The launch is notable because Apple’s Messages application is one of the company’s most tightly integrated communication products.
Apple has historically emphasized privacy and control over user data, making third-party access to messaging information a sensitive area.
The development also comes amid broader tensions between Apple and OpenAI, according to reports. Bloomberg’s Mark Gurman has raised questions about how the new integration fits into Apple’s privacy approach while the two companies are involved in a separate legal dispute.
The new feature could therefore attract attention not only from users but also from privacy advocates and Apple itself.
ChatGPT’s Mac Strategy Is Expanding
The Messages plugin follows a series of efforts to make ChatGPT more deeply integrated with macOS.
OpenAI’s desktop application already provides features such as the Chat Bar, which lets users quickly invoke ChatGPT with the Option-Space keyboard shortcut.
The company has also introduced other desktop-oriented capabilities, including computer-history features designed to help users retrieve information about their recent activity.
The direction is increasingly clear: ChatGPT is being positioned as an assistant that can understand and act across a user’s digital workflow.
The Bigger Picture
The Apple Messages plugin represents a significant expansion of what ChatGPT can do on a Mac. Instead of requiring users to copy conversations into an AI chatbot, the integration can search, analyze and summarize iMessage, SMS and RCS conversations directly through Apple’s Messages environment. It can also draft and send messages, although sending requires user approval by default.
The feature also highlights the trade-off involved in building more capable AI assistants. Giving ChatGPT access to personal communication makes it substantially more useful, but it also requires users to grant powerful permissions and carefully consider privacy and security implications. The requirement for Full Disk Access and the option to automate message sending make permission management particularly important.
Looking Ahead
The Messages integration could become an important part of OpenAI’s broader strategy to turn ChatGPT into an action-oriented desktop assistant. Searching conversations, preparing replies and retrieving information from years of message history are relatively simple examples of what becomes possible once an AI can interact directly with applications. Future versions could potentially expand the range of supported workflows while maintaining user approval for sensitive actions.
For Mac users, however, convenience will need to be balanced against privacy. The plugin has access to highly personal communications, and users should carefully review permissions and avoid enabling persistent message approval unless they fully understand the risks. If OpenAI can combine deeper system integration with strong privacy controls and reliable action confirmation, the Messages plugin could become an important step toward making AI assistants genuinely useful across everyday desktop tasks.
