Claude & ChatGPT · WhatsApp Channels
Schedule WhatsApp Channel posts and plan the week
Ask Claude or ChatGPT to post an update to your WhatsApp Channel now, schedule it for later, or plan up to 14 posts at once. Or use “Schedule a channel post” in Kaption’s Scheduled tab.
In the Kaption app for Mac and Windows now (0.97 or later); in Chrome and Edge with the next extension update.
Try asking
List my WhatsApp channels and how many posts are waiting in each.
Plan next week on my “Daily Deals” channel: one short post each weekday at 9 AM. Show me the texts before you schedule them.
Post “We open at 10 tomorrow” to my Store News channel and to my Neighbours community, a few minutes apart.
Which channel posts are scheduled? Cancel the one on Friday.
Keep your channel going without living on your phone
A channel works when it posts regularly. Write a week of updates in one sitting with Claude or ChatGPT, check the texts and times, and Kaption posts each one from your own WhatsApp when it is due. The same update can go to several of your channels and communities at once.
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 post, a schedule or a whole week. The assistant shows you the exact text, channels and times and waits for your yes.
- 04
Kaption posts on time
Each post goes out from your own WhatsApp on this computer, so keep it on with Kaption open. You can see and cancel what is still waiting.

“Schedule a channel post” lets you pick a channel or community, write the text and set the date and time, no assistant needed.
Plan and limits
Channel posts 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 post images, videos or polls?
Not yet. Channel posts are text only for now.
Which channels can I post to?
Channels you own or administer. Kaption checks again right before each post goes out; if you are no longer an admin, the post is not sent.
Does my computer need to be on?
Yes. Posts go out from your own WhatsApp in Kaption on your computer, so it must be on and connected at the scheduled time.
Can I see or cancel a scheduled post?
Yes. Ask the assistant what is waiting, or open Kaption’s Scheduled tab, and cancel any post before it goes out.
What can’t it do yet?
It can’t show channel insights or views, invite admins, approve join requests or delete a channel.
