UX/UI Principles

The tool offers a collection of 168 UX/UI design principles that are each linked to peer‑reviewed research and a total of more than 2,098 academic citations covering the period 2020‑2026. The principles are organized into six categories—including Foundations, Core Principles, Design Systems, Interface Patterns, and Specialized Domains—providing a structured reference for understanding user behavior and common interface problems.

A free AI validator lets users submit design artifacts and receive instant feedback based on the cited principles, allowing designers, product managers, developers, and solo creators to justify decisions with documented evidence. In addition, the service supplies over 600 ready‑made prompts for AI models such as Cursor, V0, and Claude, helping users generate UI concepts that adhere to the documented cognitive laws.

The offering includes a paid tier that unlocks the full library of principles for $29 per year, while the free tier provides access to the validator and a selection of prompts. The resource targets professionals who need evidence‑backed guidance to reduce guesswork and improve the reliability of their UI decisions.
