CatchUI turns interface screenshots into UI vocabulary lessons. It identifies recognizable patterns, shows where they appear, and links each result to a curated card with the proper name, purpose, tradeoffs, and when-not-to-use guidance. Save useful cards to your Library and review them with spaced repetition. Built for design students, career-switchers, PMs, and developers; bilingual in English and Chinese. Model-assisted recognition may occasionally be wrong—the catalog content is curated.
