Signal + ChatGPT integration
Connect Signal to ChatGPT
ConnectChats brings your Signal 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 Signal
ConnectChats gives ChatGPT a small set of tools. ChatGPT calls them when you ask about your Signal chats, and only for the chats you share.
-
Catch you up
Ask what you missed and ChatGPT reads your unread Signal 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 Signal 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 Signal account and confirms delivery. Auto-send only runs in chats where you switch it on.

How Signal and ChatGPT work together
ConnectChats links to your Signal account as a linked device, the same way Signal Desktop does, and brings in the chats you choose. Your phone stays your main device, and you can unlink ConnectChats from it at any time.
-
Signal in ConnectChats
One to one chats and groups are supported. Signal gives a newly linked device little or no past history, so most chats start from the moment you link. Messages are decrypted on our server so your AI app can read them, then stored encrypted with a key only your passkey can unlock. 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 Signal stays under your control
-
You pick the chats
ChatGPT only sees the Signal 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 Signal, 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 Signal messages?
Yes, once you link Signal 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 Signal messages for me?
ChatGPT can draft a reply and send it after you approve it. Messages go out from your own Signal account. You can allow automatic sending for specific chats, and it stays off everywhere else.
Is the Signal 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 Signal 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 Signal once and use it everywhere.
Does linking ConnectChats weaken Signal's encryption?
Signal still encrypts messages on their way to every device, including ConnectChats. ConnectChats is one of those devices, so it can read the messages it receives. It then stores them encrypted with a key only your passkey can unlock. If you want a chat to stay out of it, do not share it, or do not link Signal.
Will I see my old Signal messages?
Mostly not. Signal shares little or no history with a newly linked device, so expect messages from the moment you link onward.
What do I need to link Signal?
Only Signal on your phone. Open https://connectchats.com/app, choose Signal, then scan the QR code from Settings, Linked devices, Link a new device in Signal.
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.
