Native UINotes & docsby KevinXC5
Leafmark
A native WYSIWYG Markdown editor that renders math and Mermaid diagrams as you type.

About
A local Markdown editor for macOS and Windows, drawn on the GPU with MyGo's native UI: no Electron, Tauri or web view. Headings, tables, footnotes, formulas and Mermaid diagrams appear typeset as you write, with a source mode when you need the raw Markdown. Files open in tabs or from a folder workspace, and export to HTML, PDF or a Markdown copy.
