For Gnome fans, Apostrophe is a clean and intuitive Markdown editor you should try!

Apostrophe is one of the Gnome Circle Apps that provides a modern and distraction-free writing environment for Linux.

The editor supports for inputting via Pandoc’s Markdown, CommonMark, GitHub Flavored Markdown, MultiMarkdown and Plan Markdown formats.

The app has Light, Dark, and Gray (maybe) UI appearance. The ‘Hemingway Mode’ is available which will disable the backspace key. And ‘Focus Mode’ will highlight the current line, remove header and bottom bar to provide a zen-like environment when writing.

With inline preview, it formats your text automagically for you. By Ctrl+Clicking on anything, it shows popover preview, links, footnotes, equations.

Live Preview can be set to full window, right / bottom part, or a separate window. In bottom right it indicates how many words you wrote. It also counts characters, sentences, paragraphs, and read time.

And you can save you work as PDF, HTML, ODT. An advanced export dialog allows exporting to more formats including:

• LibreOffice Text Document.
• Microsoft Word(docx).
• EPUB v3.
• HTML5 Slideshow (reveal.js, DZSlides)
• LaTeX (tex)
• LaTeX Beamer Slideshow (tex, pdf)
• Textile, Texinfo, and more.
