iMessage + ChatGPT integration
Connect iMessage to ChatGPT
ConnectChats brings your iMessage chats into ChatGPT. Ask ChatGPT to catch you up, find any message and draft replies. Nothing gets sent until you approve it.
Free to start. No app to install. Every send needs your OK.
What ChatGPT can do with your iMessage
ConnectChats gives ChatGPT a small set of tools. ChatGPT calls them when you ask about your iMessage chats, and only for the chats you share.
-
Catch you up
Ask what you missed and ChatGPT reads your unread iMessage chats, then gives you the short version: who needs an answer, what was decided, what can wait.
get_messages_to_summarize -
Find any message
The address someone sent last month, the price a client agreed to, the link from a group chat. ChatGPT searches your iMessage history and quotes the message.
search_messages -
Draft replies
ChatGPT writes the reply in your tone, in the chat's language, with the context of the whole thread. You read it, edit it, and send it.
draft_reply -
Send with your OK
When you approve a draft, ConnectChats sends it from your own iMessage account and confirms delivery. Auto-send only runs in chats where you switch it on.

-
Add ConnectChats to ChatGPT
- In ChatGPT on the web, open chatgpt.com/plugins, select the plus button and choose Add custom MCP server.
- Name it ConnectChats, paste https://api.connectchats.com/mcp as the server URL and choose OAuth for authentication.
- Read the warning, select I understand and want to continue, then Create as a plugin.
- ChatGPT opens the ConnectChats sign-in page. Sign in with your passkey and allow access.
- Start a new chat, select ConnectChats and ask about your messages.
-
Link your iMessage account
- Open https://connectchats.com/app and choose Link a chat app, then iMessage.
- Install the ConnectChats relay on a Mac that is signed in to Messages with the same Apple Account as your iPhone.
- The relay pairs with your ConnectChats account using a code shown in the dashboard.
- Keep the Mac on and awake. Your chats appear in the dashboard, where you choose which ones your AI app can see.
-
Pick the chats ChatGPT can see
Every chat is listed in your ConnectChats dashboard. Share all of them or only the ones you choose. ChatGPT never sees the rest.
-
Ask ChatGPT about your iMessage
Open a new conversation in ChatGPT and ask about your chats. ChatGPT calls ConnectChats when it needs your messages.
How iMessage and ChatGPT work together
ConnectChats links to iMessage through a Mac. Apple only lets iMessage run on its own devices, so ConnectChats connects through a small relay app on a Mac that stays on and signed in to Messages with your Apple Account.

iMessage in ConnectChats
A Mac that stays on is required. Without one, iMessage cannot be connected, because Apple offers no other way in. One to one chats and group chats are supported, including SMS from your iPhone if Text Message Forwarding is on for that Mac. Messages arrive while the Mac is awake. If it sleeps or shuts down, new messages wait until it is back. Photos, videos and voice notes show up as short text descriptions, with their captions.

ConnectChats in ChatGPT
ChatGPT connects to remote MCP servers that you add as a custom plugin. You add ConnectChats once with its server address and sign in with your passkey. ChatGPT can then read, search and summarize the chats you share, and draft replies for you to approve. Custom MCP servers are added on the web. The ChatGPT help center says which plans can add one, and the list has changed several times, so check yours there. On some plans OpenAI lets custom servers read but not take actions. Reading and searching work there; drafting and sending need a plan that allows write actions. In Business and Enterprise workspaces, an admin or owner usually has to create and publish the plugin before members can use it. ChatGPT asks you to confirm before a tool takes an action, on top of ConnectChats' own draft approval.
Your iMessage stays under your control
-
You pick the chats
ChatGPT only sees the iMessage chats you share. Unshare a chat and it disappears from every AI app at once.
-
Drafts by default
ChatGPT prepares replies. You approve each one before it reaches iMessage, unless you turn on auto-send for that chat.
-
Stored messages are encrypted
Stored messages are encrypted with a key that only your passkey can unlock. We never train models on your messages.
Questions
Can ChatGPT read my iMessage messages?
Yes, once you link iMessage in ConnectChats and add ConnectChats to ChatGPT. ChatGPT reads only the chats you share, and only when you ask it something that needs them.
Can ChatGPT send iMessage messages for me?
ChatGPT can draft a reply and send it after you approve it. Messages go out from your own iMessage account. You can allow automatic sending for specific chats, and it stays off everywhere else.
Is the iMessage to ChatGPT integration free?
Yes. The free plan links two chat apps and works in every supported AI app, with no limit on what you ask. No card needed.
Do I need to install anything?
No. You add ConnectChats inside ChatGPT and link iMessage from your browser. There is no app to download and nothing runs on your computer.
Does it work with other AI apps too?
Yes. The same ConnectChats account works in ChatGPT, Claude, Grok, Manus, Muse and any AI app that supports remote MCP servers. Link iMessage once and use it everywhere.
Can I use iMessage without a Mac?
No. Apple does not allow iMessage on anything other than its own devices, so a Mac that stays on is the only way.
Does it work for iPhone SMS too?
Yes, if your iPhone forwards text messages to that Mac. Turn it on in iPhone Settings, Apps, Messages, Text Message Forwarding.
What do I need to link iMessage?
A Mac that stays on and awake, signed in to Messages with the same Apple Account as your iPhone, with the ConnectChats relay installed on it.
Can I add ConnectChats from the ChatGPT mobile app?
Not directly. Custom MCP servers are added in ChatGPT on the web. Do it once from a computer, then use ConnectChats from your ChatGPT account.
Why does ChatGPT ask me to confirm before it drafts a reply?
ChatGPT treats any tool that changes something as an action and asks first. ConnectChats then keeps the reply as a draft until you approve it, unless auto-send is on for that chat.
Will ConnectChats be in the ChatGPT app directory?
That is the plan. Once the listing is live, adding ConnectChats will take one click from the directory instead of a custom server.
