Claude & ChatGPT · WhatsApp Communities
Run your WhatsApp Community with Claude or ChatGPT
Send or schedule announcements, link and unlink groups, and ask for a summary of what happened across the community’s groups. Kaption does it from your own WhatsApp on your computer.
In the Kaption app for Mac and Windows now (0.97 or later); in Chrome and Edge with the next extension update.
Try asking
Summarize what happened in my “Class 4B Parents” community since yesterday, group by group.
Schedule an announcement in my Building community for Monday at 8 AM: “The water is off from 10 to 12.”
Create a community called “Running Club” and link my groups Sunday Runs and Track Nights.
Which groups are in my Volunteers community, and where can I post?
Every group in the community, in one place
A community ties several groups together, and keeping up with all of them takes time. With Kaption, Claude or ChatGPT can read the recent activity across the groups, write the announcement with you and send it to the announcement group at the time you pick.
How it works
- 02
Connect your assistant
Add Kaption to Claude or ChatGPT, and check that sending from this computer is on in Kaption › AI assistants › Messaging.
- 03
Ask, check, say yes
Ask for a summary, an announcement or a change to the groups. Before anything is sent or changed, the assistant shows you what it will do and waits for your yes.
- 04
Kaption sends on time
Announcements go out from your own WhatsApp on this computer, so keep it on with Kaption open. You can see and cancel what is still waiting.

Announcements
Send an announcement to the community’s announcement group now, or schedule it. Only community admins can announce.
Plan ahead
Schedule up to 14 announcements in one request, each with its own text and time.
Community digest
For the announcement group and each linked group: how many messages arrived (up to 7 days back) and the latest ones, so the assistant can sum it up.
Link groups
Link or unlink up to 20 groups at a time, and see which groups are in a community and where you can post.
Create a community
Create a community with a name and description, and link groups you administer right away.
Channels too
Send one update to several of your communities and channels at once, at least 2 minutes apart.
Plan and limits
Announcements follow the same consent, pacing and daily limits as other messages Kaption sends from your computer, and each Claude or ChatGPT request counts toward your plan like any other. See plans and prices
Questions
Is it in Chrome?
Not yet. It is in the Kaption app for Mac and Windows now (0.97 or later) and comes to Chrome and Edge with the next extension update.
Can I send images or polls?
Not yet. Announcements are text only for now.
Who can send announcements?
Community admins. Kaption checks that you can still post in the announcement group right before each announcement goes out.
What does the digest share with the assistant?
For each group: how many messages arrived since the time you choose, and the last 5 messages with their time and whether they were yours. It leaves out phone numbers and member IDs.
Does my computer need to be on?
Yes. Announcements go out from your own WhatsApp in Kaption on your computer, so it must be on and connected at the scheduled time.
What can’t it do yet?
It can’t approve join requests, invite admins or deactivate a community.
