Math editor + live preview

Enter Markdown with LaTeX math syntax. The right panel reflects live typesetting output.

Demo worksheet

Write inline equations like a2+b2=c2a^2 + b^2 = c^2.

Use display mode for derivations:

∑k=1nk=n(n+1)2\sum_{k=1}^{n} k = \frac{n(n+1)}{2}

KaTeX syntax guide

Common expressions rendered with the same KaTeX engine as the preview.

KaTeX quick syntax

  • Inline math: E=mc2E = mc^2
  • Fractions: a+bc+d\frac{a+b}{c+d}
  • Matrices: [1234]\begin{bmatrix}1 & 2\\3 & 4\end{bmatrix}
  • Integrals: ∫0∞e−x dx=1\int_0^{\infty} e^{-x}\,dx = 1
  • Summations: ∑i=1ni2\sum_{i=1}^{n} i^2

Display block:

∇⋅E=ρε0\nabla \cdot \mathbf{E} = \frac{\rho}{\varepsilon_0}
