Alloy · AI Prototyping for Product Management

Lifelike AI prototyping tool for Product Managers with an existing product Alloy is the world's first tool for prototypes that look exactly like your product. Capture any page of your web app from the browser and instantly turn it into an interactive prototype—perfect for exploring features, validating ideas, and sharing with stakeholders.

What you can do

• Capture from the browser: One click to “Capture page” on any screen of your product.

• Get lifelike results: Prototypes stay on brand and reflect your component library and design system—no off-brand mockups.

• Design by conversation: Use natural-language prompts to add features, remix flows, and refine details; switch to visual editing when needed.

• Improve with every capture: Build a reusable library as you capture more pages; results get faster and more accurate.
