Setup in 3 steps, prompts to copy, limits and privacy. Canonical: https://kaptionai.com/mcp/claude/summarize-whatsapp-chats/ Connect WhatsApp to Claude through Kaption, then ask for a summary of any chat or group by name. Claude reads the recent messages, with the text of transcribed voice notes, and tells you what was decided and what is waiting for you. ## How do I summarize a WhatsApp chat with Claude? Turn on Cloud MCP in Kaption, add https://mcp.kaptionai.com/mcp to Claude and sign in with a code on WhatsApp. Then ask “summarize today’s Sales group”: Claude finds the chat, reads its recent messages through Kaption on your computer, or asks Kaption for its own summary of up to 500 messages, and answers in the conversation. It is unlimited in your first 60 days; after that it uses your plan’s monthly credits. ## What do I need to do this in Claude? Kaption open on your computer (the extension in WhatsApp Web, in Chrome or Edge, or the Kaption desktop app) with Cloud MCP on, a Kaption account (every account starts with 60 days of Business, unlimited; after that, a plan with credits), and Claude. Setup takes three steps: 1. **Turn on Cloud MCP in Kaption.** In WhatsApp Web with the Kaption extension (Chrome or Edge), open AI Assistants (MCP) › Cloud Bridge › Enable. In the Kaption desktop app, switch on Cloud MCP in Settings. Keep Kaption open while Claude works. 2. **Add the connector in Claude.** Go to Customize › Connectors, click + Add › Add custom connector, name it WhatsApp and paste https://mcp.kaptionai.com/mcp. 3. **Sign in and switch it on.** Enter your phone number and the 6-digit code Kaption sends you on WhatsApp. Then, in a Claude chat, click + › Connectors and turn WhatsApp on. MCP server address: `https://mcp.kaptionai.com/mcp` (Streamable HTTP, OAuth 2.1). Full Claude setup guide: https://kaptionai.com/mcp/claude/ ## What should I ask Claude? Copy a prompt, paste it into Claude and change the names to your own chats and contacts. - Summarize today’s messages in the Sales group: decisions, open questions, and anything addressed to me. - What happened in my chat with Marta this week? Give me five bullet points. - Which of my unread chats need a reply from me today? One line each. - Summarize the last 200 messages in the Family group and list any dates or plans mentioned. - Summarize the Project Alpha group since Monday, then draft a short reply I can paste that answers the open questions. ## What can Claude do here, and what can’t it? ### It can - Find a chat or group by name and read its recent messages, with the text of voice notes Kaption has transcribed. - Get Kaption’s summary of a conversation, built from up to 500 recent messages, or write its own from the messages it read. - List your unread chats and tell you which ones look like they need you. - Keep going from the summary: set a reminder, or draft a reply for you to check. - Work on Claude Free, Pro, Max, Team and Enterprise. Free can add one custom connector, which is enough for Kaption. - Work in Claude Code too: claude mcp add --transport http whatsapp https://mcp.kaptionai.com/mcp ### It can’t - Read locked chats. They are never visible to the assistant. - Summarize audio that has no transcript: it reads text, so transcribe the voice notes in Kaption first. - Work while Kaption is closed. Open WhatsApp Web with the extension, or the desktop app, or the tools answer “Extension not connected”. - Promise a perfect summary. AI can miss sarcasm, inside jokes and who replied to whom, so check the messages before you act on anything important. ## What leaves my computer? Claude receives the messages it reads, or the summary Kaption returns. When Kaption writes the summary, only the text of those messages goes to Kaption’s AI, without your name, number or contacts, and it is never used to train AI models. Kaption’s relay at mcp.kaptionai.com checks your sign-in and passes each request to Kaption on your computer, which runs it against your WhatsApp and sends back only the answer; the relay does not keep your chats. What comes back, such as message text, names and numbers, goes to Claude, which handles it under its own privacy terms. Locked chats are never visible to the assistant, and you can disconnect at any time. ## How many credits does my plan include? Claude and ChatGPT are unlimited in every account’s first 60 days; after that they need a plan, counted in credits per calendar month: Lifetime local AI 50, Pro 250, and Business 500 with its 2 numbers plus 250 for each extra number, shared by all its numbers, the plan to pick when an assistant uses WhatsApp every day. Business Agent includes them with fair use. A read uses 1 credit, a send 2 and a summary 3. See plans and prices: https://kaptionai.com/pricing/ ([pricing.md](https://kaptionai.com/pricing.md)). ## Questions ### Can Claude summarize a WhatsApp group? Yes. Name the group in your request. Claude looks it up with Kaption, reads its recent messages and summarizes them. For a busy group, say how far back to go, for example “since this morning” or “the last 300 messages”. ### How far back can it read? As far back as you ask, in batches: Claude can ask Kaption for earlier messages before a date. Kaption’s own summary uses up to 500 recent messages. Each batch is a read and uses 1 credit, so long reads use more of your monthly credits. ### Does it work with WhatsApp Business? Yes. Kaption works with personal and WhatsApp Business accounts. With more than one number connected, Claude can pick the account to read from. ### Do I need a paid Claude plan? No. Claude Free can add one custom connector, which is enough for Kaption. On Team and Enterprise, an owner adds the connector once in Organization settings › Connectors and each member clicks Connect. ## Related - [Summaries in WhatsApp Web](https://kaptionai.com/summarize-whatsapp-chats/) - [Summarize chats and groups in ChatGPT](https://kaptionai.com/mcp/chatgpt/summarize-whatsapp-chats/) - [Summarize chats and groups in Cursor](https://kaptionai.com/mcp/cursor/summarize-whatsapp-chats/) - [Full Claude setup guide](https://kaptionai.com/mcp/claude/)
