ColaMD is a free, open-source Markdown editor for Windows, macOS, and Linux that provides a distraction-free writing environment. Its WYSIWYG editor displays formatted Markdown directly without requiring a separate preview pane. Documents automatically refresh when external applications, scripts, or AI coding agents modify their files. Users can browse Markdown folders, navigate document outlines, and switch to raw source editing. The application supports interactive task lists, mathematical formulas, syntax highlighting, and Mermaid diagrams. Twelve built-in themes and customizable fonts provide a personalized reading and writing experience. Search and replace tools simplify document editing. Finished documents can be exported as PDF, HTML, Word, or PNG files while preserving their formatting.
