Frequently Asked Questions

Does it support GitHub-flavored Markdown?

It supports the common Markdown syntax used across most platforms, including tables and code fences, via the marked parser — check specific platform extensions separately if you rely on less common syntax.

Is my Markdown text uploaded anywhere?

No — the entire parsing and rendering process happens locally in your browser, so your text never leaves your device.

Can I preview a full README file?

Yes — paste your entire README content, however long, and the preview will render the full document live as you edit it.

Does it support syntax highlighting for code blocks?

Code blocks render with standard Markdown code-fence formatting; specific syntax highlighting depends on the parser configuration, so treat this as a formatting preview rather than a full-featured code editor.

Can I use this to draft a blog post before publishing?

Yes — many blogging platforms and static site generators accept Markdown directly, so previewing here first lets you catch formatting issues before pasting into your actual publishing platform.
