MultiMarkdown
Composer

MultiMarkdown Composer is a text editor specifically designed for writing in MultiMarkdown (or regular Markdown).

By using an editor built around Markdown/MultiMarkdown, you can focus on the *writing*, rather than worrying about formatting and styles. Composer's intelligent tools provide automatic support while you write -- organize your document with the Table of Contents, quickly insert links, images, etc. with the References sidebar, and quickly review CriticMarkup edits.

Features:

• Read and write files
• Intelligent editing support -- "smart pairs", automatic formatting of Markdown block structures (lists, blockquotes, tables), easily create links and images, and much more
• Live HTML preview
• Supports MultiMarkdown v6 (including regular Markdown compatibility mode)
• Built-in support for MathJax and syntax highlighting javascript libraries
• CriticMarkup support, including live change tracking and including your edits in the preview
• Automatically cleans up Markdown formatting to quickly fix problems when copying text from other sources
• Typewriter Mode to keep the cursor in the center of the screen
• Auto Zoom to make the most use of the window, regardless of what size you make it
• Sync MultiMarkdown metadata tags with macOS file tags automatically
• File comparison -- compare two files and convert the differences into CriticMarkup to easily handle file revisions shared from other users
