Everything you need to
ship the perfect site

From a blank prompt to a live, downloadable HTML website in under a minute. No templates. No drag-and-drop. Pure AI.

Typewriter AI Builder

Watch Demure Ultra write your website character by character in a real-time typewriter view. See exactly what the AI is creating as it happens.

👁

Live Preview

A split-pane interface shows the AI code on the left and a fully rendered live preview on the right — updating every few seconds as the build progresses.

🎙

Voice Feedback

Built-in Web Speech API reads status updates aloud. Hear "Demure Ultra is writing your hero section" without lifting a finger.

🗺

Plan Mode

Toggle Plan Mode to make the AI outline a full strategy — sections, color palette, content — before a single line of code is written.

📦

Project Upload

Upload a .zip of an existing project. Sync analyses the structure and uses it as context to generate a matching, consistent website.

💬

AI Chat Assistant

Beyond building, Sync's chat interface supports streaming conversations with code blocks, inline previews, and syntax highlighting.

One-click Download

Every generated website is a single self-contained HTML file. Download it, host it anywhere, or iterate again — no lock-in.

🎨

Model Selection

Choose from four Demure AI models — Ultra, Pro, Fast, or Lite — to balance quality vs. speed for your specific use case.

🔐

API Access

Enterprise plan includes full REST API access. Integrate Sync's AI building capabilities directly into your own products and workflows.

2

Choose your AI model

3

Watch it build
