Frequently Asked Questions

What is GitHub Flavored Markdown (GFM)?

GFM is GitHub's extension of standard Markdown that adds support for tables, task lists, strikethrough text, and autolinks. It's the most widely used Markdown variant for documentation and README files.

Is my content saved anywhere?

No. All processing happens in your browser. Your markdown content is never sent to any server.

Can I export to HTML?

Yes! Use the "Copy HTML" button to copy the raw HTML source, or "Copy Rich Text" to paste formatted content directly into emails, Google Docs, or other rich text editors.
