About Rune
Rune is a focused, fast Markdown editor for desktop. In one pane, your Markdown formats the moment you type — only the line you're on shows raw source. Code, Mermaid diagrams, KaTeX math, and tables render right where you write them, while the page stays calm. Local-first (plainmd files), built on Rust so it opens instantly and stays small. Korean/CJK is first-class. Free & open source (MIT) for macOS, Windows, and Linux.
