WhatsApp AI agents for businesses
A WhatsApp AI agent replies to the messages customers send to your business’s WhatsApp, at any hour and in their language. It answers questions, takes bookings and appointments and, when a person is needed, hands over the conversation with everything that has already been discussed.

How it works inside
What happens when a customer messages
Each piece does one job and hands over to the next, just like an automation workflow. Here’s how yours works, step by step.
- Trigger: New message (WhatsApp)
- AI agent: WhatsApp AI agent (Understands, solves) — Knowledge, Memory, Tools
- Action: Booking made (Calendar)
- Action: Order status (Store or ERP)
- Action: Reminder (The day before)
- Action: Chat passed to team (With a summary)

The same agent, by voice and in writing
It can be the same agent that answers your phone, with the full context of the conversation: customers never have to repeat themselves.
Hands over to your team at the right moment
When a conversation needs a person, it passes it on with a summary of what has been discussed.
In your customer’s language
It replies in the language customers write in, without you having to find someone who speaks it.

Questions
Frequently asked questions
What is a WhatsApp AI agent?
It is an assistant that chats with your customers on WhatsApp. It understands what they write in everyday language, responds with your information and handles tasks such as making a booking, scheduling an appointment or giving an order update.
Does it replace the team that answers messages?
No. It takes care of the everyday, repetitive questions and passes to your team the conversations that need a person, with the context already gathered. Your team can spend its time on the cases that call for it.
Can it connect to the tools we already use?
Yes. The Nertel team connects it to your calendar, booking software or CRM, so everything that happens on WhatsApp is recorded without manual re-keying.
When is a WhatsApp AI agent not worth it?
If you receive few messages and can reply straight away, it adds little. It makes the difference when messages arrive out of hours, when they pile up at peak times or when most of them ask the same thing.
