Manage WhatsApp Communities with ChatGPT
Ask ChatGPT to set up a community, add or remove groups, send or schedule announcements, or tell you what happened across its groups today. It shows you every change and announcement before it goes ahead.

How do I manage a WhatsApp Community with ChatGPT?
Connect WhatsApp to ChatGPT with Kaption’s MCP server and ask “what happened in the School Parents community today?” or “announce Friday’s meeting in the community”. ChatGPT reads the groups through Kaption on your computer and, for any change or announcement, shows you the exact text, community and time and waits for your yes. It works in the Kaption app for Mac and Windows now, and in Chrome and Edge with the next extension update.
What do I need to do this in ChatGPT?
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 ChatGPT. Setup takes three steps:
- 02
Create the app in ChatGPT
Turn on Developer mode in Settings › Apps › Advanced settings (Connectors on some plans), click Create, name it WhatsApp, paste https://mcp.kaptionai.com/mcp and choose OAuth.
- 03
Sign in and pick it in a chat
Enter your phone number and the 6-digit code Kaption sends you on WhatsApp. Then pick the WhatsApp app from the tools menu in a ChatGPT conversation.
What should I ask ChatGPT?
Copy a prompt, paste it into ChatGPT and change the names to your own chats and contacts.
What happened in the School Parents community since yesterday? Sum up each group in two lines.
Announce in the Building community: “Water will be off on Thursday from 10 AM to 2 PM.” Show me the text before you send it.
Create a community called Running Club and link my groups Morning Runs and Weekend Trails.
Schedule announcements in the Football community for the next three Saturdays at 9 AM. Let me check them first.
Give me a table of the groups in my Neighbours community: group, messages since Monday, and what people talked about.
What can ChatGPT do here, and what can’t it?
It can
- List your communities, their announcement group and linked groups, and which ones you can post in.
- Create a community, and link or unlink up to 20 of your groups at a time.
- Send an announcement now, or schedule up to 14 in one request, in a community you administer.
- Count the messages in each group and read the latest ones, from the last 24 hours up to 7 days, so ChatGPT can tell you what happened.
- Work wherever your ChatGPT plan and workspace allow custom MCP apps. If you don’t see Developer mode, ask your workspace admin or check OpenAI’s help center.
It can’t
- Approve join requests, invite admins, add people or deactivate a community.
- Announce in a community you don’t administer, or post images, polls or other media: announcements are text only.
- Act without asking. ChatGPT shows you each change and the exact text, community and time first, and a scheduled announcement is not proof it went out.
- Read locked chats, or work while Kaption is closed on your computer.
What leaves my computer?
Kaption reads the community and its groups on your computer. For a digest, ChatGPT receives message counts and recent texts, with no participant numbers. Scheduled announcements wait in Kaption on your computer and go out from your WhatsApp there.
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 ChatGPT, 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: Lifetime local AI 20 actions a week, Pro 250 credits a month, 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
Questions
Can ChatGPT add groups to my community?
Yes, groups you administer. Ask it to link or unlink groups, up to 20 at a time, and it tells you which worked and which did not. It can also create a new community with those groups.
Does the digest show who said what?
It shows the latest messages in each group and whether they were yours, with no phone numbers or participant ids. ChatGPT writes the summary from those messages and the counts.
Where does this work today?
In the Kaption app for Mac and Windows, version 0.97.0 or newer, and in WhatsApp Web with the Chrome or Edge extension after its next update. Changes and announcements also need “Assistants can send messages” turned on in Kaption.
Which ChatGPT plan do I need?
One that lets you add a custom MCP app with developer mode. OpenAI changes which plans and workspaces allow it, so if the option is missing, check OpenAI’s help center or ask your workspace admin.
