Meet Cadu: The AI That Builds Your Website Over WhatsApp
What if you could build and manage a real website just by sending a message? That's exactly what Cadu does — and it's weirder and more useful than it sounds.
Cadu is an AI assistant that lives in WhatsApp. You describe what you want, and it builds your site. Change your mind? Send another message. Want to update your opening hours at 11pm from your phone? Send a message. No laptop required, no dashboard to log into, no plugin to update.
How It Actually Works
Under the hood, Cadu is doing a lot. It maintains a real codebase for your site — HTML, CSS, proper templates — hosted on fast infrastructure with clean URLs and good SEO out of the box. When you send it a request, it reads the relevant files, makes the changes, and deploys them. All of that happens in seconds while you're staring at three dots on your phone.
The conversation is the interface. There's no form to fill in, no toolbar to learn. You just talk to it like you'd talk to a developer friend who happens to be available at all hours and never charges by the hour.
"I just texted it 'make the button red' and it did. I've never felt so powerful."
Built for Real Businesses
Cadu isn't a toy. It handles multilingual sites, custom domains, contact forms, blog posts, galleries, menus, price lists, and more. It knows about accessibility, mobile layouts, and performance. It'll suggest improvements when you're not sure what to do next.
The sweet spot is small businesses and individuals who need a real online presence but don't want to deal with the usual overhead. A restaurant owner updating their menu between lunch and dinner service. A freelancer tweaking their portfolio on the bus. A local shop that finally has a website because someone showed them WhatsApp.
The Part That Surprises People
Most people expect a template picker with drag-and-drop boxes. What they get instead is a conversation — and at first that feels strange. Then they ask for something specific, something they'd normally have to hire someone for, and it just... does it. That's usually the moment it clicks.
The site you get isn't a locked-down template. It's real code, structured properly, that you can take anywhere. Cadu just makes editing it feel like texting.
