+# MarkdownPointer
+
+**Vibe writing for Markdown.** Point at anything, tell AI to fix it.
+
+MarkdownPointer renders your Markdown and lets you click any element — headings, code blocks, table cells, Mermaid diagram nodes, KaTeX math — to copy a `filepath:line` reference. Paste it into your AI prompt, and the AI knows exactly where to look. This npm package bundles the MCP server and the viewer app — no separate installation needed.
