scikit-learn is a Python module for machine learning built on top of SciPy and distributed under the 3-Clause BSD license.
It gives you a seamless experience as both a reader and a writer. It removes the preview window, mode switcher, syntax symbols of markdown source code, and all other unnecessary distractions. Replace them with a real live preview feature to help you concentrate on the content itself.
MacDown is an open source Markdown editor for OS X, released under the MIT License. It is heavily influenced by Chen Luo’s Mou.
Markdown parser done right. Fast and easy to extend. Supports the CommonMark spec + syntax extensions + sugar (URL autolinking, typographer).
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.
