How it works

Three steps. That's it.

No onboarding screens, no CMS to learn, no developer to call. Your WhatsApp is your admin panel.

01

Send a message

Text the Calu number on WhatsApp with what you want changed - in plain language, exactly like you'd tell a person.

~10 seconds
02

AI makes the edit

Calu understands your message in context and applies the change to your site precisely. If something is unclear, it asks first.

~5–15 seconds
03

Your site goes live

Changes deploy to our global CDN instantly. You get a WhatsApp confirmation with a link to the live site.

Instant

What you get

Everything you need. Nothing you don't.

Calu is designed for people who run businesses, not people who run websites. Radical simplicity is the product.

WhatsApp as your admin panel

The interface you already use every day. No new app, no login, no learning curve. If you can send a text, you can manage your site.

Seconds, not hours

Changes go live instantly. No waiting for a developer, no support tickets, no CMS workflow. Intent to live site in under 30 seconds.

Undo, always

Every change is versioned. Say "undo" at any point to revert your site to its previous state - no consequences, no pressure.

Always online

Your site is hosted on a global CDN - fast and reliable for visitors everywhere, with zero infrastructure to manage.

No credentials to lose

Identity is tied to your WhatsApp number. No forgotten passwords, no account lockouts, no support emails about login issues.

AI that knows your site

Calu reads your site before every edit so it understands context. It makes precise changes and knows when to ask before acting.

Pricing

Simple, transparent pricing.

One plan. One price. No setup fees, no per-edit charges, no surprises.
