Refero

Refero is a design research tool that provides a vast library of real-world product screenshots and user flows. Designers and product teams use it to see how successful applications handle specific design challenges. You can browse by page type, such as dashboards or landing pages, or by UI elements like modals and navigation bars. A key feature is the ability to search by image, where you can upload a screenshot to find visually similar designs from the database.

The platform organizes its content into clear categories including Page Types, Flows, UX Patterns, and UI Elements. It also offers an MCP (Model Context Protocol) server, which allows AI agents to access this design data. This makes it a useful resource not just for human designers, but also for AI systems that need reference material for generating or evaluating designs. The library is updated weekly with new examples from various industries.

This tool is particularly valuable for UI/UX designers, product managers, and developers who are building new features or applications. It helps teams make informed design decisions by showing them proven examples instead of starting from a blank slate. Whether you're designing a subscription paywall, a user onboarding sequence, or a data-heavy dashboard, Refero provides concrete inspiration from actual products.
