Product Information
What is Alloy?
Alloy is an AI prototyping platform that mirrors your existing product so you can capture screens and flows directly from your browser and then modify them using a conversational interface. It uses generative AI to propose design changes, generate new components and preview the results instantly, helping you iterate on new features without rebuilding from scratch.
How to use Alloy?
- Install the Alloy browser extension and record your product’s screens and flows directly from your application.
- Start a chat with the AI and describe the changes or features you want; Alloy will generate prototypes on top of your captured product.
- Iterate with the AI until the prototype matches your requirements, then share or export the designs for development.
Core Features
- Capture your real product and turn it into an editable prototype.
- Conversational interface to modify screens and user flows using generative AI.
- Rapid preview of changes with exportable assets for developers.
Use Cases
- Product designers testing new features on existing applications.
- Founders prototyping new flows without needing design expertise.
- Teams refining UI/UX using AI to reduce iteration cycles and collaborate faster.
