FAQ

What is GitHub-Flavored Markdown (GFM)?
GFM is an extension of standard Markdown used by GitHub. It adds support for tables, task lists, strikethroughs, and autolinks, all of which are natively supported by our previewer.
Does this tool support mathematical formulas?
Yes. Our workbench integrates KaTeX for high-performance LaTeX math rendering. You can use $...$ for inline math and $$...$$ for block formulas.
How does Synchronized Scrolling work?
When enabled, scrolling the Markdown editor will automatically move the preview pane to the corresponding section, keeping your source and result perfectly aligned.
Is my documentation private?
Absolutely. Like all DevToolkit utilities, the Markdown engine runs 100% client-side. Your text never leaves your browser and is never stored on our servers.
