ChatGPT on Mac: iMessage Integration & AI Reply Plugin

ChatGPT on Mac can now read and reply to iMessages using a new plugin. This integration allows ChatGPT to interact with iMessage, SMS, and RCS conversations on a Mac. Users can search past messages, summarize conversations, draft replies, and send messages directly. This feature is available across all ChatGPT subscription tiers, including free accounts. It works within the ChatGPT Work and Codex modes of the macOS desktop application. The plugin requires an Apple silicon Mac and specific system-level permissions. These include macOS Full Disk Access, contact access, and automation controls. OpenAI has provided example prompts for its use. The integration uses established macOS system technologies like AppleScript and Accessibility settings. This means it relies on officially documented Apple automation interfaces. For privacy, ChatGPT asks users to confirm message content and recipients before sending. Users can grant persistent approval for specific chats, but OpenAI advises against this, warning it removes the final review opportunity. This matters because it gives Mac users new AI communication tools for their messages.
