WhatsApp Business with the Mujib AI agent, what works and its limits
The Mujib agent works the same way on a WhatsApp Business number and on a regular WhatsApp number: it reads your customers’ text messages, voice notes and photos, answers them from your knowledge base, and hands the conversation to your team when needed. It joins the number as a linked device, so the number keeps working on your phone.
The linking steps are in Connect WhatsApp. This page covers what happens after that: what the agent understands, how it replies, and where its limits are.
Does the agent work with WhatsApp Business?
Section titled “Does the agent work with WhatsApp Business?”Yes. A WhatsApp Business app number and a regular WhatsApp number link to Mujib the same way, from Linked devices in the app, just as WhatsApp Web does.
- You do not need a new number, and you do not move your number to another service.
- WhatsApp keeps working on your phone, and you see the agent’s replies there as the customer sees them.
- One number serves one business in Mujib, and your subscription sets how many numbers you can connect.
How is this different from WhatsApp’s official platform? See WhatsApp Business API or the WhatsApp Business app.
Which kinds of WhatsApp messages does the agent understand?
Section titled “Which kinds of WhatsApp messages does the agent understand?”The agent understands text, voice notes and photos, and records everything else in the conversation for you to see.

What happens if I reply from my phone myself?
Section titled “What happens if I reply from my phone myself?”The agent stops replying in that conversation, because your reply means someone on your team has taken it over. Other conversations are not affected.

Is there a 24-hour window on WhatsApp?

- Calls: the agent does not answer voice or video calls; they stay with you on your phone.
- Videos and files: the agent answers only the text sent with them.
- Delete for everyone: from the inbox you can delete a message Mujib sent, for the customer too, within 47 hours of sending it. If the customer deletes their own message, it shows as deleted in the inbox as well. See Download and delete media.
How do I turn the agent off on one WhatsApp number?
Section titled “How do I turn the agent off on one WhatsApp number?”Each connected number has a Replies & agent strip on the Channels page, and that is where you stop replies on that number alone.
- Open Channels and find the number in the WhatsApp numbers card.
- In the Replies & agent strip, press Edit.
- Turn Auto-reply off, then press Save.
- Confirm with Turn off.
From then on, that number’s messages go to Inbox and your team answers them; other numbers and channels stay as they are. The same strip lets you pick which Agent answers the number when you have more than one.
