When current available Markdown editors are almost all for general writers, Mou is different: It's for web developers. Syntax highlighting, live preview, sync scroll, fullscreen mode, auto save, powerful actions, auto pair, custom themes and CSS, HTML and PDF export, enhanced CJK support. I know, it's exactly the app you want.


Mou comes with lots of handy actions. All you need for writing in Markdown is here, and blazing fast!

Enhanced CJK Support

Write in Chinese, Japanese or Korean? No problem! Mou fully supports CJK Characters!

View Control

Toggle live preview, fullscreen mode, and layout orientation. Write in Chinese traditional way using vertical layout.

Custom Themes

Choose a built-in theme you like, or create your own.

Custom CSS

Custom CSS for Live Preview and HTML Export is also possible.

Incremental Search

Mou features incremental search with pattern matching.

Auto Completion

Mou features auto completion for English words. Press `Esc` key to show a list of possible completions.

Export HTML

Export HTML anytime you want, with or without CSS.

Words Counter

Beautiful counter, counts words, characters and bytes.

Command Line

Launching Mou from Terminal, type open -a Mou. To open file, type open or open -a Mou

Post on and Tumblr

Publish your article to or Tumblr directly within Mou, with a single command.

Write Todo Lists & Solarized Theme

Download Stuart Frisby's TopMarks CSS, gracefully convert Mou to your favorite GTD app.

Ethan Schoonover's Solarized color scheme is great, thankfully, John Yanarella made a Solarized Theme for Mou.

And that's not all.
