Element Brief

Element Brief is a developer productivity tool that lets you click any element on any webpage and instantly copies a structured, AI-friendly summary to your clipboard.

PERFECT FOR:
- Test automation — Get stable locators (data-testid, CSS selectors, accessibility queries)
- AI-assisted coding — Paste element context directly into ChatGPT, Claude, or Copilot
- Accessibility audits — See WCAG AA contrast ratios and accessible names at a glance
- Design QA — Check computed styles, colors, and font properties instantly

FEATURES:
- Smart locator generation — Prioritizes test IDs, stable IDs, accessibility selectors, then fallback CSS
- Tailwind-aware class filtering — Won't dump 50 utility classes; keeps only meaningful ones
- WCAG contrast calculation — Computes real contrast ratio with parent background traversal
- Bounding box & children summary — Know exactly where elements are and what they contain
- Shadow DOM support — Works with open shadow roots (notes when elements are inside)
- Clipboard fallback — Shows modal for manual copy if clipboard is blocked

PRIVACY FIRST:
- 100% local — No analytics, no tracking, no remote calls
- Minimal permissions — Only activeTab and scripting
- No background activity — Only runs when you click the icon
