ChatGPT Mac app gets Messages plugin to read and send iMessages

On August 21, OpenAI rolled out an Apple Messages integration plugin for the ChatGPT Mac desktop app, also covered by TechCrunch. Once authorized, ChatGPT can search and read a user's full message history, review conversation context, draft and send replies on the user's behalf, and analyze chats to surface insights about contact frequency and topics.

Confirmed

ChatGPT can draft and send replies on the user's behalf; official example prompts include checking a calendar to confirm a dinner time and extracting info from yesterday's messages (@Polymarket, @testingcatalog)
The feature can categorize, analyze and edit messages, offering insights on contact interaction frequency and topics; per @emmanuelvivier, iMessage, SMS and RCS are all supported
The integration ships as a Messages plugin, reportedly available in ChatGPT Work and the Codex desktop app (@testingcatalog, @dkundel)

Why it matters

@Dimillian notes the update raises privacy concerns: letting an AI read full message histories and send messages on users' behalf opens some of the most private personal data to a third-party assistant at scale
For OpenAI, it marks a key step in ChatGPT's evolution from a general chat tool toward a system-level personal assistant, with deeper Apple ecosystem integration boosting its Mac presence
