Alloy App

Creating lifelike product prototypes usually takes hours—if not days. But what if you could turn your actual web product into a prototype within minutes? That’s exactly what Alloy App, an AI prototyping tool, offers. It lets you capture your product’s interface, modify it with AI, and build prototypes that look exactly like your real product—no designer dependency or mockups needed.

Whether you're a product manager, founder, or UX strategist, Alloy could be the fast lane to better user validation and stakeholder feedback.

What is Alloy App?

Alloy App is a browser-based AI-powered prototyping tool that allows you to transform your existing web app interface into editable, high-fidelity prototypes. Using AI, it helps you create new features or adjust flows while maintaining full design system consistency—without touching a single line of code or exporting from Figma.

Key Features

1. Browser-Based UI Capture: Instantly capture any screen from your web app using the Alloy browser extension. It automatically identifies and saves components into a UI library.
2. AI-Powered Prompting: Want to redesign a page or add a new feature? Just type your idea in natural language—Alloy uses AI to generate the changes within your interface style.
3. Brand Design Matching: Alloy replicates your product’s fonts, colors, button styles, and layout perfectly. Every prototype looks like part of your live product.
4. Component Library Recognition: It understands your product’s existing components and reuses them intelligently, saving you from rebuilding things from scratch.
5. One-Click Sharing: Share realistic prototypes with stakeholders, teammates, or users for immediate feedback. No logins or complex tools needed.
6. Over 20+ Integrations: Alloy connects with tools like Jira, Notion, Slack, and more—making it easier to fit into your existing workflow.
7. Zero Setup: No Figma exports or design tokens needed. Just capture your app and start building.
