Three steps. That's it.
No onboarding screens, no CMS to learn, no developer to call. Your WhatsApp is your admin panel.
Text the Calu number on WhatsApp with what you want changed - in plain language, exactly like you'd tell a person.
Calu understands your message in context and applies the change to your site precisely. If something is unclear, it asks first.
Changes deploy to our global CDN instantly. You get a WhatsApp confirmation with a link to the live site.
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.
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.
Changes go live instantly. No waiting for a developer, no support tickets, no CMS workflow. Intent to live site in under 30 seconds.
Every change is versioned. Say "undo" at any point to revert your site to its previous state - no consequences, no pressure.
Your site is hosted on a global CDN - fast and reliable for visitors everywhere, with zero infrastructure to manage.
Identity is tied to your WhatsApp number. No forgotten passwords, no account lockouts, no support emails about login issues.
Calu reads your site before every edit so it understands context. It makes precise changes and knows when to ask before acting.
Simple, transparent pricing.
One plan. One price. No setup fees, no per-edit charges, no surprises.
