KaTeX

The KaTeX WordPress plugin enables you to use the fastest TeX math typesetting engine on your WordPress website. You can include TeX inside a [katex]...[/katex] shortcode or in a Gutenberg block. Either way the math will render beautifully on your website. When using Gutenberg blocks, the equations will render immediately inside your editor!

Equations in blocks or using the [katex display=true]...[/katex] shortcode will render on page in display mode–with bigger symbols–centered on their own line.

For compatibility with other LaTeX plugins, this plugin optionally supports [latex]...[/latex] shortcodes.
