Does the agent think for itself?

It chooses an answer from what you gave it. What was not defined should not be closed by it.

Can it start without a website?

Yes. The customer writes to the number. The site only points to it.

What a WhatsApp agent is for a business

A WhatsApp agent is software that answers on the business number, inside the rules you gave it. It fits questions that repeat. It does not fit a promise, a discount, or a complaint.

What it actually does

A customer writes. The agent checks whether there is a prepared answer: hours, address, what the service includes, or an opening in a calendar. If there is a match, it answers. If there is not, it says it is handing the chat over, and you receive it.

Without a list of answers and a handoff rule, there is no agent. There is a text box that can invent. The work starts from what it is allowed to say.

A WhatsApp agent compared with a person
	Person	Agent
Hours and address	Answers when free	Answers immediately, if it was written
An unapproved price	Decides	Does not close it
A complaint	Handles it	Hands it over
Night	The next day	Only what is inside the rules

What it is not

It is not a hired employee. It does not close a deal unless the rule allows it. And it is not a system that replaces a CRM, a calendar, and a service desk at once.

Ordinary WhatsApp, where the owner replies, is not an agent. An agent that answers customers on its own sits on the WhatsApp Business API, with a verified business account.
