share-the-mark

Mark up any live web page, then hand a clean Markdown changelog and an annotated screenshot straight to your AI assistant — or to the share-the-mark CLI your agent is watching.

Annotate the live DOM, export agent-ready

  • Five focused tools — callout, text, arrow, highlight, and element — drawn directly over the real page. Marks are content-anchored, so they survive scroll, resize, reflow, and re-renders.
  • One-click export copies a stable Markdown changelog (element selectors + your notes) plus an annotated PNG — as a single clipboard item to paste anywhere.
  • Hand off to an agent via the local share-the-mark CLI/daemon, with a Claude Code skill included, so a coding agent can act on your visual feedback.
  • Embed without the extension — drop the @share-the-mark/embed widget into a dev/staging build, or let the CLI drive a Playwright browser.

Start with Install the extension, then Usage.
