OpenAI has added an Apple Messages integration to ChatGPT on Mac, in an August 20 update. ChatGPT can now search chats, summarise conversations, draft replies and, with user approval, send messages. OpenAI rolled out this feature in its latest update, making it available through the Messages plugin for ChatGPT Work and Codex on desktop.
This integration covers iMessage, SMS, and RCS chats on Mac. ChatGPT can pull information from messages, flag conversations needing follow-up, find birthdays and spot possible spam. It links messaging to other tasks, such as checking a calendar before suggesting dinner times. Letting an AI read and act on personal messages raises privacy and security questions, made sharper by Apple’s lawsuit against OpenAI last month over alleged trade-secret theft.
How ChatGPT Reads and Drafts in Apple Messages
ChatGPT can now read and search conversations in Apple’s Messages app on Mac. Rather than scrolling through long threads, a user can ask ChatGPT to find information or summarise a conversation.
OpenAI listed several examples. ChatGPT can scan a calendar and reply with free times for dinner next week. It can suggest follow-ups from yesterday’s chats, pick out birthdays in messages and add them to your calendar, or flag suspicious messages as possible spam. ChatGPT can also draft a reply using context from Messages, without the user copying text into a separate window.
The feature is available in ChatGPT Work and Codex on desktop. Users install Messages from Plugins > Public. Plugins in general are becoming the key to ChatGPT connecting with other apps and services. OpenAI says the new Messages integration works on all ChatGPT plans in the desktop app for macOS, but right now it’s only available on Apple silicon Macs, not Intel machines.
Install Messages from Plugins > Public, then try prompts like:
— ChatGPT (@ChatGPT) August 20, 2026
– Check my calendar and reply to [name] with a few times I'm free for dinner next week
– Suggest follow ups from yesterday in messages
– Find birthdays in @ messages and add them to my calendar
– Find potential…

Sending Messages Raises Privacy Questions
Reading user chats is one thing, but letting AI actually send messages raises bigger privacy and control questions. Sending requires user approval by default. ChatGPT prompts for approval of both the text and the recipients before a message goes out. Users can choose Allow once, or Always allow sending to this chat to skip future prompts for that conversation.
OpenAI warns against enabling persistent approval, since it removes the last chance to review a message before it sends. A message thread is also untrusted input, which makes standing send permission a prompt-injection risk.
Isn’t this like a privacy nuclear bomb though

OpenAI makes it clear that user consent is required, and the plugin doesn’t create a searchable index of all chats. The plugin runs locally on your Mac and uses built-in macOS tools like AppleScript and Accessibility to interact with Messages. Setup requires granting Full Disk Access in System Settings, along with permission for contacts and automation tools. The plugin does not let users reach ChatGPT remotely through Messages. It works only with the Messages app on the same Mac.
apple messages integration is a nice feature. it's also a very efficient way to make sure you keep paying for chatgpt work instead of switching. the features that feel like gifts are usually retention mechanics

OpenAI’s update has more upgrades too. Pinned chats now sync between ChatGPT’s desktop app and iOS, Codex users can send read-only snapshots of local threads, and site owners get new collaboration and URL management tools.
