CriticUI

Hey Product Hunt 👋 We’re excited to introduce CriticUI — an AI-powered UX-critiquing engine that shows you how real users actually interact with your website, and surfaces where design, content or flow breaks down before you ship. For the past few months, we’ve been driven by one simple but urgent question: Why are designers and developers shipping faster than ever… while understanding what users actually do remains painfully slow and expensive? On the engineering side, we’ve seen tooling that accelerates testing, deployment, QA, and iteration. But on the design side? Many teams still depend on slow, expensive, and often inconsistent methods — manual usability studies, ad-hoc feedback, gut-feel rather than data. Iteration velocity has soared, yet design understanding has barely kept pace. That’s where CriticUI comes in. We built it to bring automation, clarity, and shared insight into how design changes impact user behavior, so designers and developers can iterate fast and confidently.
