  2. The engine immediately compiles the Markdown into HTML.
  3. Review the visually styled preview on the right side in real-time.

Frequently asked questions

Which flavor of Markdown is technically supported?

It supports the universal core specification shared by all flavors: headings, emphasis, fenced code blocks, lists, blockquotes, and links.

Can I safely paste raw HTML into the editor?

Yes. Any pasted HTML is strictly escaped and rendered visually as plain text rather than executed, providing absolute protection against XSS payloads.

How do I save my document?

You can simply copy the raw text from the left editor. The preview side exists purely to validate your formatting logic.
