UX/UI Principles

About

Access free AI tools that evaluate designs using 168 UX principles supported by research. While Cursor, v0, and Claude produce visually appealing interfaces, they often disregard core UX fundamentals such as Hick's Law, cognitive overload, and absent feedback loops. Five complimentary tools are provided: AI Validator, UX Smell Detector, Flow Checklists, over 600 AI Prompts, and a Parts Checklist. No registration is required. The Principles Library, available for $29 annually, provides full access to all 168 principles with examples and prompts. This resource is supported by more than 2,098 citations and is available in English and Spanish.
