ChatGPT’s new Mac plugin reads iMessages and offers message search, summaries, and analysis

# What the Messages plugin does

Once enabled, the plugin supports three practical tasks: send a text, search and summarize messages, and analyze conversations with someone to produce tone descriptions and communication suggestions.

# How to set it up

Open ChatGPT on Mac and check for the latest update via the ChatGPT menu. In Settings, open Plugins, browse for "Messages," and click Install. The app will prompt you to grant access to your Mac's Messages. Allowing access is required for search, summarize, and analysis features to work.

You can compose a message in ChatGPT and tell it to send to a named contact using the Messages plugin. ChatGPT prepares the text but will ask for confirmation before sending, unless you choose to always allow sending for that chat. This duplicates existing functionality in Apple Messages, but it centralizes drafting and allows you to ask for help with wording before you send.

# Search and summarize message threads

# Analyze your conversations

The analysis command — for example, "Analyze my messages in @Messages with [name of person]" — prompts ChatGPT to describe the tone, recurring topics, and communication patterns in that thread. The app can suggest alternative phrasing to reduce defensiveness or make a message more likely to produce a productive reply. The author's example: a complaint about canceled dinner plans triggered advice that the original wording might invite defensiveness and a recommended rephrase.

# Practical use cases

• Drafting or polishing sensitive texts where tone matters.
• Quickly summarizing months of exchanges on a specific topic (appointments, pet care, travel plans).
• Spotting recurring patterns in how you communicate with a specific person.

# Privacy and permissions

Functionality requires ChatGPT to read your Messages on the Mac. That access enables search, summaries, and conversation analysis, so enabling the plugin involves trade-offs: you must trust the app with the contents of your text messages to get these features. The plugin requests explicit permission on the Mac before it can operate.

# When it helps and when it's redundant

Sending a plain text via ChatGPT duplicates what Messages already does, so the main value is in search, summarization, and analysis. Those features save time when you want an overview or a tone check across multiple messages without manually scanning entire threads.
