About this tool

Most LLMs return Markdown by default. This tool previews it as clean HTML so you can spot broken lists, unbalanced fences, and mismatched headings before you ship the output.

How it works

  1. Paste Markdown into the left pane.
  2. The right pane renders it live using a safe subset (headings, emphasis, lists, code, links, blockquotes).
  3. Copy either the Markdown or the rendered HTML.

When to use it

  • Sanity-checking Markdown returned by GPT-4 or Claude.
  • Drafting blog posts before pasting them into a CMS.
  • Building README snippets and previewing GitHub-style rendering.
