NameThat: The Visual Dictionary of UI

What it is — A visual dictionary that lets you describe a UI element in plain language (or point at it) and get back its real technical name, so you can prompt coding agents precisely instead of vaguely.

Key points

• Covers native-app and web-in-a-shell vocabulary separately, since the same-looking element often has a different name on each platform.
• Includes comparative guides (e.g. AppKit vs SwiftUI naming) and a translation table across 60+ UI elements.
• Double-press any word on the site for a plain-English definition; command-palette search (⌘K) for quick lookup.
