Refero.ai: The Ultimate AI-Integrated Design Research Library

What is it?

Refero is a comprehensive design research library and AI-integrated tool built specifically for UI/UX designers and developers. It helps professionals find inspiration and improve AI-generated design outputs by providing real-world examples rather than generic mockups.

Release Date

• Initial Launch: March 15, 2023
• Refero 2.0: August 17, 2023
• Refero 3.0: June 20, 2024
• Refero 4.0: May 29, 2025
• Refero MCP (AI integration): March 10, 2026

How Does It Work?

Refero operates on two main fronts:

• For Designers: It offers a massive, searchable library containing over 135,000 real-world UI/UX screens and 10,000+ user flows from top-tier, successful products. Designers can filter these by page type, UI elements, or specific design patterns to find practical inspiration.
• For AI Agents (Refero MCP): Refero uses the Model Context Protocol (MCP) to connect your AI agents (like Claude or Cursor) directly to its database. Instead of guessing how to design an interface, the AI agent can query Refero to study real-world layouts and patterns before it builds, resulting in highly accurate and professional outputs.

How to Use It

• Manual Research: Visit refero.design. Use the search bar and filters to look up specific patterns (like a 'pricing table' or 'login dashboard') and browse the curated collection of real product interfaces.
• AI Integration: To use the automated features, you need a Refero Pro subscription. You integrate the Refero MCP with your AI agent using the provided configuration. Once connected, your AI agent can automatically perform design research on your prompts, pulling relevant UI patterns to guide its coding and design output.
