The open-source markdown editor

Proton Screenshot

Easy, Fast, Open

Built on Electron, open on GitHub.

As a college student, I needed a way to quickly take rich notes in class. I have long been a proponent of the Markdown Language, so I decided to download MacDown for easy rendering and viewing. However, upon an OS update on my local machine, the Markdown rendering broke. Thus, I decided to build my own open-sourced version that is supported on Windows, OSX, and Linux machines using the Electron Framework.
