Does it match GitHub's rendering?

Very closely. We use the same GFM dialect and similar CSS reset so the output looks familiar.

Will math expressions render?

Yes — inline `$…$` and block `$$…$$` expressions are rendered via KaTeX.

Can I export the preview as PNG?

Not directly in this tool. For image exports, check the `/summary/pdf` tool for similar workflows.

Is the CSS customizable?

Not in the basic tool. The preview uses a neutral GitHub-like stylesheet.

Does it support mermaid diagrams?

Not yet — mermaid rendering is on the roadmap for a future update.

Markdown edge cases we handle

Faithful rendering

The preview matches what GitHub and most blog platforms render — no custom styles bleed in.

Code-block highlighting

Fenced code blocks with language hints get syntax highlighting in the preview.

Math expressions

Inline and block math expressions (`$x^2$` and `$$x^2$$`) are rendered using KaTeX.

Image lazy-load

Images load lazily with alt-text fallback shown until the image loads.
