Signal + Gemini integration
Connect Signal to Gemini
ConnectChats brings your Signal chats into Gemini. Ask Gemini 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 Gemini can do with your Signal
ConnectChats gives Gemini a small set of tools. Gemini calls them when you ask about your Signal chats, and only for the chats you share.
-
Catch you up
Ask what you missed and Gemini 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. Gemini searches your Signal history and quotes the message.
search_messages -
Draft replies
Gemini 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 Gemini 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 Gemini
The Gemini web app can add custom apps from an MCP server URL on eligible accounts. Add ConnectChats once, sign in with your passkey, and pick it with @ in any prompt where you want Gemini to see your chats. Google limits custom apps in Gemini to people 18 or older in the US, signed in with a personal Google account, in English, with Keep Activity on. Work and school accounts are not supported. Custom apps are connected in the Gemini web app, then also work in the Gemini mobile app. The same ConnectChats account works in every AI app, so the chats you already linked are available in Gemini without linking them again. ConnectChats only sees the chats you choose to share, and it asks for your approval before any reply is sent.
Your Signal stays under your control
-
You pick the chats
Gemini only sees the Signal chats you share. Unshare a chat and it disappears from every AI app at once.
-
Drafts by default
Gemini 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 Gemini read my Signal messages?
Yes, once you link Signal in ConnectChats and add ConnectChats to Gemini. Gemini reads only the chats you share, and only when you ask it something that needs them.
Can Gemini send Signal messages for me?
Gemini 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 Gemini 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 Gemini 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 use ConnectChats with Gemini today?
Yes, on accounts where Gemini offers custom apps. Add ConnectChats with https://api.connectchats.com/mcp in the Gemini web app under Settings, Connected Apps, then sign in with your passkey.
Will it work with a Google Workspace account?
No. Google does not offer custom apps in Gemini for work or school accounts, so use ConnectChats with a personal Google account.
