On August 20, OpenAI rolled out an update to the ChatGPT desktop app that moves a line: ChatGPT can now get at your messages. On Apple Silicon Macs, the new Apple Messages plugin reads and searches iMessage, SMS, and RCS – and can prepare replies or send them.
What the plugin does
You can ask ChatGPT to search your messages, catch you up on a thread you missed, or draft a reply. It’s available in ChatGPT Work and in Codex on the desktop. The important bit: before any message goes out, ChatGPT asks for explicit approval. That’s the kind of safeguard you want – nobody wants an AI texting the wrong person unprompted.
Not the only update
The Apple Messages plugin didn’t arrive alone. In the same batch, OpenAI pulled in a few more things: pinned chats now stay in sync between the desktop app and iOS, so you can keep an important conversation handy on both Mac and iPhone. Codex threads can be shared as a read-only snapshot. And owners of ChatGPT Sites on Plus and Pro can change their site URL without redeploying – the old address redirects automatically.
My take
Access to your own messages cuts both ways. Handy, no question – “summarize what went down in the family group” genuinely saves time. But your messages are about the most private thing on a machine. Requiring approval before sending is the bare minimum. Even so, I’d look carefully at which app is reading along before I leave that switched on for good. The trend is clear: the assistants are moving out of the chat window and straight into the apps we use every day. Claude Cowork is walking the same path, just through skills and connectors. Convenience and control have to stay in balance.
