OpenAI has released a new plugin for ChatGPT on Mac that integrates with Apple Messages. This plugin allows ChatGPT to search through your messages, draft new ones, analyze conversations, and send replies. Users can install the Messages plugin from the ChatGPT Plugins interface. It supports iMessages, SMS, and RCS messages. The plugin is available for ChatGPT Work and Codex on the desktop version of ChatGPT for Apple silicon Mac users. Sending a message requires explicit user approval by default, and OpenAI advises against persistent approval. To function, the integration needs Full Disk Access and access to contacts and automation tools within macOS System Settings. The plugin likely utilizes AppleScript and Accessibility settings to operate. Apple's official involvement is not specified, and the release comes amidst ongoing legal battles between Apple and OpenAI. The Messages integration is not functional in regular ChatGPT chats.
