Your name, logo and colours on every screen, email and member app. Your own web address with a branded sign-in, or your own domain. You can even give Duke another name.
01Duke in Brand & domain
Customers talk to your business. Give the assistant the name you like: it introduces itself with it on WhatsApp, and your brand is on everything it sends.
Who decides
On WhatsApp, customers are told they're talking with your business's assistant, and can ask for a person at any time.
Name, colours, the assistant's name and the email footer, with a preview first.
Adding your own domain means DNS records at your provider and a click on Verify. That's not something Duke does.
02In Brand & domain
What Your brand & domain does, part by part, on screens from our live demos.
Your look
Set your business name, logo, favicon and brand colour. Emails go out with your brand, and AI replies carry your business's name. Rename the assistant if you'd like it to be called something else.
With Duke: ask it to change the colour, the footer or its own name, with a preview first.
Brand
Your address
