Inline + block LaTeX, server-rendered.
$f(x) = \frac{1}{1+e^{-x}}$ and it renders inline as you write. Block math gets full display treatment. KaTeX renders on the server — readers never see a flash of unrendered backslashes.Empirq is built for technical writers who've watched their math break on general-purpose newsletter platforms, their code lose its formatting in blogging tools, or burned a weekend on a static-site theme that still doesn't render KaTeX inline. We built the fix.
No reaching for plugins. No copy-paste hacks. No "workaround for math rendering." All of this ships in the editor on day one.
