01Duke in WhatsApp
Put Duke on duty on your WhatsApp and it replies to customers who write to you, from what you've told it. In the app, it drafts replies and template messages for you to send.
Who decides
On duty, Duke replies to people who wrote first, about their own business with you. It starts on drafts your team sends with one tap, until you let it answer on its own.
Ask Duke to answer a customer in your words. It writes it, and you approve the exact text before it's sent.
Describe a template and Duke writes it with the right placeholders, then submits it to Meta for review once you approve.

What WhatsApp does, part by part, on screens from our live demos.
Your own number
Each business connects its own WhatsApp Business number on Meta's Cloud API. Your access token is stored encrypted and only its last four characters are ever shown.
With Duke: Duke on duty answers on this same number, under your assistant's name.

On the customer's page
Incoming and outgoing messages sit on the contact's Messages card, with a composer right there. A number you've never seen becomes a contact on its own, and numbers are saved in international format.
With Duke: it reads a customer's message history before drafting, if your role may read it.
Automations and agents
An automation can send an approved WhatsApp template as one of its steps. An AI agent can be allowed to send approved templates on its own, up to a limit per run, as long as the message is entirely your template with no words written by the AI.
