MarkdownPointer

A Markdown viewer designed for AI-assisted document review. Click any rendered element to copy its file path and line number to clipboard - perfect for pointing AI to specific locations in your documents.

When reviewing AI-generated Markdown, click any element (headings, paragraphs, code blocks, Mermaid nodes, etc.) to instantly copy a reference like:

C:\docs\report.md:42

Paste this into your AI prompt to precisely point to the location that needs revision.
