Markdown+

Write in plain text. See the finished document.

A fast, native writing workspace that keeps your Markdown and its rendered result together—from a quick note to a folder full of long-form work.

The source stays simple. The result does not have to.

Markdown+ gives plain-text writing the navigation, rendering, and publishing tools of a much heavier editor—without turning your files into a proprietary format.

Your writing, rendered as you type.

Keep the editor and preview side by side, focus on either pane, or switch layouts as your work changes. Scrolling stays synchronized, and matching text can take you straight from source to result.

Markdown that can think.

Define a name, date, snippet, or formula once and reuse it throughout a document. Variables can transform text, evaluate expressions, and update every reference automatically.

Code, equations, tables, and images—already handled.

Highlight code in more than 140 languages, typeset LaTeX with MathJax, turn CSV or TSV data into Markdown tables, attach local images, and control image width without leaving the editor.

A complete home for serious Markdown work.

Folders become workspaces

Open a folder directly, then browse, search, rename, sort, and edit its Markdown files from one native workspace.

Outline every long document

An automatically updated table of contents keeps headings visible and makes large files easy to navigate.

Choose the layout you need

Work in the editor, the preview, or both. Customize toolbars, font sizes, themes, and comfortable line lengths.

Keep files and assets portable

Edit Markdown, TextBundle, and TextPack documents, with local images and attachments that stay with the writing.

Export, share, or publish

Print or share directly, export with assets to HTML or PDF, and publish to Ghost without rebuilding attached media by hand.

Automate the repetitive parts

Use Shortcuts actions to convert Markdown text or files to HTML and evaluate expressions with your own variables.
