The free AI website builder
that builds your site for you.
Chat with AI to build a brand-new, multi-page site — or instantly refactor your existing website into a clean, modern design. On-brand, customizable, ready to publish.
Two ways to get a great site
Start from a conversation, or start from your current site. Either way you get a modern, editable result.
Build with AI
Describe your business in plain words. AI asks a few smart questions, then generates a full multi-page website — copy, layout, and real photos included.
- Conversational, no forms to fill in
- Multi-page with real navigation
- Live editing & AI tweaks per section
- Themes, fonts & colors in a click
- 🔎 Auto-SEO — titles, descriptions & markup written for you
Takes about a minute to first preview.
