Frequently asked questions

What is GitHub Flavored Markdown (GFM)?

GFM is GitHub's extended version of standard Markdown. It adds tables, fenced code blocks with syntax highlighting hints, task lists (- [ ] checkbox), strikethrough text (~~text~~), and autolinks. Most documentation platforms — GitHub, GitLab, Notion, Slack — support GFM.

Is my content sent to a server?

No. The Markdown is rendered entirely in your browser using the marked.js library. Nothing you type is uploaded or logged.

Can I use this to preview README files?

Yes — paste the contents of any README.md and get a preview that closely matches how GitHub renders it. Tables, code blocks, and heading anchors all render correctly.

How do I create a table in Markdown?

Use pipes and hyphens: | Col 1 | Col 2 | on one line, then | --- | --- | as the separator row, then data rows. Column alignment can be set with colons: | :left | center: | :right: |.

What's the difference between Markdown and MDX?

MDX is Markdown extended with JSX — it lets you embed React components inside Markdown files. Standard Markdown (and this previewer) doesn't support JSX. MDX is used by documentation frameworks like Nextra, Docusaurus, and Next.js MDX pages.
