What you write is what you see.
Markdown Magic renders every line as you type. Only the line with the cursor shows its raw Markdown — no split view, no separate preview. Mermaid diagrams and LaTeX formulas appear right below their source.
Version 1.0 · Requires macOS 27 or later
Everything you need to write in Markdown
A focused editor that stays out of your way, with the tools technical writing needs.
-
Live preview in one view
Headings, emphasis, lists, quotes, code, links and tables are rendered in place. Move the cursor onto a line to edit it; move on and it renders again.
-
Mermaid diagrams
Write a mermaid code block and the flowchart or sequence diagram is drawn below it, updated with every keystroke.
-
KaTeX formulas
Put LaTeX between $$ or in a math code block, and the formula is typeset instantly.
-
Tables and task lists
Tables become clean grids, task lists get clickable checkboxes, and highlights stand out.
-
Images inline
Images from your Mac or the web appear right in the document. Save diagrams and formulas as PNG, with or without a background.
-
Toolbar and shortcuts
A formatting toolbar and Format menu with a keyboard shortcut for every command.
-
Outline and recent files
Jump between headings in the outline, and reopen documents from the sidebar.
-
Six themes
Standard, Light, Dark, Sepia, Solarized and Nord, with your choice of font and size.
-
Five languages
Available in English, German, French, Italian and Spanish, with a built-in Markdown guide.

Your files stay yours
Documents are plain .md files that open in any editor. Markdown Magic never rewrites your Markdown: rendering only changes how the text looks, so what you save is exactly what you typed. Mermaid and KaTeX are built in, so diagrams and formulas render completely offline.
