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

How WhatsApp and Le Chat work together
ConnectChats links to your WhatsApp account as a linked device, the same way WhatsApp Web and the desktop app do. Your phone stays the main device, and you can unlink ConnectChats from it at any time. Direct chats and group chats both come through, and you choose which ones your AI app can see.
-
WhatsApp in ConnectChats
Each linked chat starts with its last 200 messages, then every new message arrives as it is sent. Direct chats, groups and replies are supported. Photos, videos and voice notes show up as short text descriptions, with their captions. Your phone does not need to stay on, but WhatsApp unlinks companion devices when the phone has been offline for about 14 days. Open WhatsApp on your phone now and then to keep the link. ConnectChats uses one of the four linked device slots WhatsApp gives each account. The free plan links 2 chat apps and keeps messages for 30 days.
-
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 WhatsApp stays under your control
-
You pick the chats
Le Chat only sees the WhatsApp 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 WhatsApp, 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 WhatsApp messages?
Yes, once you link WhatsApp 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 WhatsApp messages for me?
Le Chat can draft a reply and send it after you approve it. Messages go out from your own WhatsApp account. You can allow automatic sending for specific chats, and it stays off everywhere else.
Is the WhatsApp 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 WhatsApp 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 WhatsApp once and use it everywhere.
Does my phone need to stay online for WhatsApp to work?
No. ConnectChats keeps receiving messages while your phone is off or out of signal. WhatsApp does sign out linked devices if the phone stays offline for about 14 days, so open WhatsApp on it from time to time. If that happens, link it again from https://connectchats.com/app.
Can it read WhatsApp group chats?
Yes. Groups come through like direct chats, with each sender's name. Every group is listed in your dashboard, and you decide which ones are shared with your AI app.
Does it work with the WhatsApp Business app?
Yes. The WhatsApp Business app supports linked devices, so it links with the same QR code or pairing code. The WhatsApp Business Platform (the Cloud API used by large companies) is a different product and is not supported.
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.
