What is Markzen?

Markzen is a desktop editor for lightweight markup languages — Markdown and six others — with a live, fully styled preview. You write plain text marked up with simple punctuation on the left, and Markzen renders it as formatted HTML on the right as you type.

What sets it apart from an ordinary Markdown editor is the round-trip. Markzen reads seven markup languages, renders 30 live extensions (diagrams, charts, mathematical formulas, music scores, chess boards, QR codes) inside the document, and exports to more than twenty formats — ebooks, Word, PowerPoint, LaTeX, Jupyter notebooks and more. Write once, hand the result off as almost anything. The converter is built in, so there are no external tools to install.

You can open an existing file or just start typing — there's no requirement to open a file first.
