WhatsApp chat summarization via ConnectChats
Users can now connect WhatsApp chats to AI applications like ChatGPT and Claude using ConnectChats to generate custom message summaries.
The remote Model Context Protocol server links to messaging platforms to fetch unread threads, according to the ConnectChats blog.
OpenAI previously offered an official WhatsApp number, 1-800-ChatGPT, which allowed users to chat with the bot directly. Meta discontinued that service on January 15, 2026, after updating its WhatsApp Business terms, as reported by 9to5Mac.
The older tool could not read unread messages sitting inside group chats or project threads without manual copying. Meta AI offers a built-in summarization feature within single WhatsApp conversations using private processing, but it does not support cross-chat queries.
How ConnectChats processes unread messages
ConnectChats operates as a remote MCP server based on the open-source Model Context Protocol standard developed for AI applications, according to modelcontextprotocol.io documentation.
When a user asks about missed messages, the AI calls the get_messages_to_summarize tool to retrieve unread threads. The system retrieves messages per call, turning media files into short text captions while leaving final summary generation to ChatGPT or Claude.
The free tier connects two chat apps without requiring credit card details. Paid plans cost $9 per month and support all chat applications supported by ConnectChats, while preserving user messages for 30 days.
Setting up the connection in ChatGPT and Claude
Connecting WhatsApp requires scanning a QR code via the linked devices menu in the mobile app, using one of the four available device slots permitted by WhatsApp.
Users add the custom MCP server in ChatGPT by entering the server URL at chatgpt.com/plugins. Claude supports the same server through its custom connector settings found under the user customization menu.
Shared chats remain private unless explicitly enabled by the user. ConnectChats stores encrypted messages behind passkeys and excludes conversation data from AI training models.
Frequently asked questions about ConnectChats
Can ChatGPT read my personal WhatsApp messages automatically?
ChatGPT cannot access WhatsApp without configuration. Users must add the ConnectChats MCP server and explicitly share specific chat rooms before any reading can occur.
Do other group members know I am using an AI summary?
Summarization requests trigger no notifications inside WhatsApp group chats. The generated output appears exclusively inside the user’s AI application window.
How long do messages stay stored on the platform?
Disconnecting WhatsApp removes all associated chat rooms and stored messages immediately.
