what it is

CatchUI tells you what that UI thing is called. Drop in a screenshot and it names every pattern inside it (bottom sheet, segmented control, toast…) with the evidence for each name, then saves them to your library for spaced-repetition review. Behind it is a curated bilingual (English / 简体中文) catalog of 50 UI patterns, with component names for SwiftUI, UIKit, Compose, Flutter and HTML. The catalog is also a free MCP server: add https://catchui.com/api/mcp to Claude, ChatGPT or Cursor. No sign-up, no API key.
