  MarkLayer lets you annotate any webpage and share it instantly.
  
  Draw freehand, add shapes, arrows, highlights, and text on top of any site. Drop comments anywhere on the page. Pick any element to grab a stable selector with computed styles and the framework component (React, Vue, Svelte) — paste it straight into Cursor or Claude. Measure dimensions and gaps between any two elements without opening DevTools.
  
  Share a link — anyone can see your annotations and collaborate in real time. No extension required on their end.
