The plugin can also search and analyze your messages and give you a list of, say, who you exchange the most messages with, which spam messages you can delete, or what messages need follow-ups.
OpenAI does say to be careful with permissions, as the plugin is required by default to get your approval before it sends any messages in your name. Without this setting, things can quickly get out of hand, so they recommend you keep it on.
— Persistent approval removes your final chance to review a message before ChatGPT sends it as you. Use it only when you accept that risk, OpenAI warns in its instructions.
The plugin runs locally on the user’s Mac and «doesn’t create an index of someone’s messages,» according to TechCrunch.
ChatGPT with Messages is free and available on all plans in the ChatGPT desktop app for macOS on Apple Silicon, and it can read and reply to anything Messages can receive. It does not, however, work the other way — and won’t let you interact with ChatGPT through SMS.
