OpenAI today announced a new Apple Messages plugin for ChatGPT on Mac, enabling the AI to search messages, draft replies, analyze conversations, and send messages directly. The plugin is available in the ChatGPT Plugins interface under Public and supports iMessages, SMS, and RCS messages.

OpenAI suggests prompts like checking calendars for dinner availability, suggesting follow‑ups from yesterday, finding birthdays to add to calendars, and identifying potential spam. Sending a message requires user approval by default, and OpenAI warns against granting persistent approval.

For the integration to function, ChatGPT needs Full Disk Access in System Settings, plus access to contact names and automation tools. The plugin uses AppleScript and Accessibility settings; Apple's involvement in development is unknown. Notably, Apple and OpenAI are currently litigating over alleged trade‑secret theft.

Messages integration works in ChatGPT Work and Codex on the desktop app but not in regular ChatGPT chats. It is available to all ChatGPT users with an Apple silicon Mac.
