MarkText
Free WYSIWYG markdown editor for all three desktop platforms.
MarkText is a free, open-source markdown editor that renders formatting inline as you type — a WYSIWYG experience over plain markdown files, with source-code and typewriter modes when you want them.
It supports GFM plus math, front matter, Mermaid diagrams, and paste-from-HTML to markdown conversion, and exports to styled HTML and PDF. Runs on Windows, macOS, and Linux.
