What is CriticMarkup?

CriticMarkup is a way for authors and editors to track changes to documents in plain text. As with Markdown, small groups of distinctive characters allow you to highlight insertions, deletions, substitutions and comments, all without the overhead of heavy, proprietary office suites.

What do I need before I start using CriticMarkup?

Nothing but knowledge of the syntax. We've compiled a helpful guide right here.

What tools work with CriticMarkup?

MultiMarkdown Composer 2.1 beta

We're pleased to announce that the latest beta of Fletcher Penney's MultiMarkdown Composer has full support for CriticMarkup. Watch the video below to get an idea of what you can do with this powerful tool.

The CriticMarkup Toolkit

We've designed the CriticMarkup syntax to work with Markdown, MultiMarkdown and HTML but it's compatible with most plain text formatting conventions. We also put together a toolkit with some nice-to-have resources for several popular applications.

  • BBEdit Plugin
  • Sublime Text Plugin
  • Keyboard Maestro Macros
  • TextExpander Snippets
  • OS X System Services
  • Command Line Preprocessor

You can download the complete CriticMarkup toolkit from Github.
