Live Markdown preview
Marked provides live preview for Markdown documents on macOS, helping writers see formatting and structure while they edit content in their editor of choice.
Marked 3
Marked 3 is a native macOS app for live Markdown preview, proofreading, and export to PDF, HTML, DOCX, EPUB, and more. It also supports DOCX round-tripping and custom processing workflows for users who need more than a basic viewer.
Overview
Marked 3 is a native macOS app for live Markdown preview, proofreading, and export. It is designed for people who write in Markdown and need a separate viewing, checking, and publishing layer rather than a full text editor.
The help documentation shows that Marked works with common Markdown variants such as GitHub Flavored Markdown, CommonMark, Kramdown, and MultiMarkdown, and can also be extended to other processors. That makes it useful for writing, reviewing, and preparing Markdown content for a range of outputs, including PDF, HTML, DOCX, and EPUB.
Beyond preview, Marked supports document-focused workflows such as navigation, statistics, spelling and grammar checks, annotations, custom styles, and automation. The DOCX and Custom Processor help pages show that it also handles Word files and rule-based preprocessing or processing for more tailored publishing pipelines.
Features
Proofreading and review tools
The app supports proofreading-oriented workflow features and the help site organizes tools for reading, writing, document navigation, statistics, spelling and grammar, and annotations.
Multi-format export
Export support includes PDF, HTML, DOCX, EPUB, and other formats named on the product site, making it useful for drafting and publishing workflows.
DOCX round-tripping
The DOCX documentation explains that Marked can import DOCX files, convert them to Markdown, and export Markdown back to DOCX with headers, footers, change tracking, and math handling.
Custom processors and rules
Custom Rules let users match files by filename, path, content, metadata, or tree context and then run preprocessors, processors, or commands based on those rules.
Workflow integration options
The app exposes workflow options such as custom styles, URL handling, AppleScript support, command line use, streaming preview, and a JavaScript API.
Use cases
Preview writing in a separate workspace
Write Markdown in another editor and keep Marked open as a live preview and proofreading surface so you can check structure, formatting, and readability without switching to a full editor.
Publish to different output formats
Prepare content for publication by exporting finished Markdown to PDF, HTML, DOCX, or EPUB, with Word-specific handling available for styles, headers, footers, and change tracking.
Round-trip between Word and Markdown
Work with DOCX documents when your workflow moves between Word and Markdown, using Marked to convert DOCX into clean Markdown or export Markdown back into a DOCX file.
Apply custom processing rules
Build automated or conditional document workflows by matching files on name, path, content, metadata, or related files and then running preprocessors, processors, or commands.
Connect to external writing tools
Integrate Marked into a broader writing toolchain with supported app integrations, command line usage, AppleScript, URL handling, or streaming preview.
