domsy.io

domsy.io is an AI companion for rapid prototyping of web apps and user interfaces directly in your browser. It turns ideas into working prototypes without setting up a dev environment or spending time on manual layout work.

Prototype instantly in the browser

Domsy generates a single file that combines HTML, CSS, and JavaScript, so you can preview results immediately without build tools, installs, or deployment. AI-made changes appear right away in the visual designer, making iteration and quick fixes easier.

AI designer with a verification loop

To reduce misunderstandings, domsy.io uses a “verification loop” that helps the AI confirm your intent. It asks for clarifications when needed, checks the output against your request, and adjusts the code to better match what you described.

Import existing pages

With Content Portability, you can bring any URL into Domsy Designer. The AI analyzes the page structure and content so you can edit, adapt, and extend an interface based on an existing site or layout.

• Generate a single HTML/CSS/JS prototype file
• Edit and iterate in a visual designer with instant updates
• Import any URL to reuse and evolve existing UI content
