Write LaTeX math with instant preview — snippets for fractions, integrals, matrices, and copy-ready output
Write equations for reports, theses, Jupyter notebooks, Overleaf, Notion, or GitHub Markdown and see them rendered instantly by KaTeX. Use the snippet buttons to learn syntax — fractions, summations, integrals, matrices, piecewise cases, Greek letters — then copy the source in the format your destination expects. Rendering errors show in red instead of failing, so you can debug incrementally.
