On August 20, 2026, OpenAI introduced the Apple Messages plugin within the ChatGPT desktop app for macOS. This plugin allows ChatGPT to read, search, and interact with iMessage, SMS, and RCS conversations on Mac, as well as draft or send messages via the Messages app. Users need to enable corresponding permissions in both the ChatGPT app and Mac system settings. OpenAI emphasizes that not all messages will be indexed, and any operations require explicit user consent.
