OpenAI is extending ChatGPT further into the Mac desktop experience with a new Apple Messages integration that allows the assistant to search conversations, summarize chats, draft replies and, with permission, send messages on a user’s behalf.
The feature is notable because Apple’s messaging ecosystem has historically been difficult for third-party services to access in any meaningful way. On supported Macs, ChatGPT Work and Codex can now interact with conversations available inside the Messages app, including iMessage, SMS and RCS threads.
That opens up several practical use cases. Users can ask ChatGPT to locate an older conversation, pull out key details from a long thread, prepare a response or send a message without manually switching between apps. The integration is available across ChatGPT plans, although its reach is currently fairly narrow.
For now, the Apple Messages plugin works only through the Apple Silicon version of the ChatGPT desktop app for macOS. It is not available from standard ChatGPT conversations on the web or mobile, and it cannot be used through the Codex CLI or IDE extension. That makes this less of a universal Messages connector and more of a Mac-specific productivity feature.
OpenAI is also putting permission controls around outgoing messages. By default, users must approve both the message content and the intended recipients before anything is sent. A user can grant ongoing permission for a specific conversation, after which future messages in that thread can be sent without repeated confirmation.
That convenience will also make permission management important. Giving an AI assistant access to private conversations is a much more sensitive proposition than asking it to summarize a document or draft an email. The usefulness is obvious, but so is the need for users to understand exactly which conversations and actions they have authorized.
The Messages integration arrives alongside several smaller ChatGPT and Codex updates. OpenAI is expanding Computer History on macOS to ChatGPT Pro users in the European Economic Area, Switzerland and the UK. The feature is designed to let ChatGPT reference activity across apps and websites used on the Mac.
Codex users can also create read-only snapshots of conversations and share them through a link. These shared versions exclude tool calls as well as shell inputs and outputs. Pinned Codex chats are now synchronized between the ChatGPT desktop app and iOS when both use the same account, although Android support is still missing.
Meanwhile, ChatGPT Sites users on Plus and Pro plans can change the URL of a hosted site without redeploying it, with the previous address redirecting automatically.
Taken together, the updates point to OpenAI’s broader direction for ChatGPT on desktop: less of a standalone chatbot and more of an assistant that can act across the apps people already use. Apple Messages is one of the clearest examples of that shift so far, but it also raises the bar for how carefully those permissions need to be handled.
