Mark Text provides a simple cross-platform markdown editor that permits note-taking as well as real-time preview and formatting of markdown code.

It is designed to be a straightforward option to utilize for multiple job applications like plain text, web pages, documents, etc. Everything can be easily exported to HTML or PDF.

Mark Text comes packaged in a clutter-free UI to keep your experience on track with no distractions. However, it will remind some of Notepad, but do not let that fool you as far as functionality for specific tasks. It also allows for some mild customization to make it your own, like the dark theme or the various view types available from the drop-down menus.

One nice feature is the ability to activate focus mode, which highlights the current paragraph. You can use the various hotkeys or special characters to change font styles, insert images or links, and other elements. There is a help section with numerous helpful points.
