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. • Share instantly: Send a link to teammates or customers for quick review and feedback. ➤ Built for modern product teams Bring ideas, insights, and customer requests straight into Alloy from the tools you already use via integrations—so you can go from signal to prototype in minutes. ➤ Privacy & security Enterprise-grade protections: encryption in transit and at rest, annual third-party penetration testing, SSO (SAML/OIDC) on Enterprise, and SOC 2 Type II in progress. ➤ How it works • Install the extension and sign in. • Open your app and click “Capture page.” • Prototype and share—iterate by prompt or visual edits and send a link. ➤ Permissions Alloy only captures the pages you choose when you activate the extension and click “Capture page.” Data is stored securely in your Alloy workspace.
