Signal + Le Chat integration
Connect Signal to Le Chat
ConnectChats brings your Signal chats into Le Chat. Ask Le Chat 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 Le Chat can do with your Signal
ConnectChats gives Le Chat a small set of tools. Le Chat calls them when you ask about your Signal chats, and only for the chats you share.
-
Catch you up
Ask what you missed and Le Chat 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. Le Chat searches your Signal history and quotes the message.

Draft replies
Le Chat 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.

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 Le Chat 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 Le Chat
Le Chat adds custom MCP connectors, including on the free plan, and ConnectChats works as one. Add it once, sign in with your passkey, and Le Chat by Mistral can catch you up on the chats you share. Only an admin can add connectors in Le Chat. On Free, Pro and Student plans, that is the account owner. On Team plans, ask your admin. Le Chat detects the sign-in method itself and supports OAuth sign-in, which is what ConnectChats uses. The same ConnectChats account works in every AI app, so the chats you already linked are available in Le Chat 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
Le Chat only sees the Signal chats you share. Unshare a chat and it disappears from every AI app at once.
-
Drafts by default
Le Chat 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 Le Chat read my Signal messages?
Yes, once you link Signal in ConnectChats and add ConnectChats to Le Chat. Le Chat reads only the chats you share, and only when you ask it something that needs them.
Can Le Chat send Signal messages for me?
Le Chat 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 Le Chat 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 Le Chat 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 Le Chat today?
Yes. Open Connectors, add a Custom MCP Connector named connectchats with https://api.connectchats.com/mcp, then sign in with your passkey.
Will it work on the free Le Chat plan?
Yes. Mistral offers custom connectors on its free plan, so you can add ConnectChats there as the account owner.
