  • The free online version is a limited preview without backups, comments, writing targets or PDF export.

ghostwriter

  • macOS support is unofficial and community-provided: there is no installer, so the app has to be compiled from source.

  • No mobile or web version is listed.
  • Export to other formats relies on processors such as Pandoc or MultiMarkdown.

Key features

Calmly Writer

WYSIWYG Markdown
Markdown is rendered as it is typed, so the syntax is never on screen: headings, tables and lists look formatted. Selecting text brings up a toolbar.
Focus mode and full screen
A focus mode and a full-screen mode, each with a keyboard shortcut, strip the window down to the text being written.
Counts and writing targets
Shows word and character counts with custom targets, plus reading time and a table of contents built from the document's headings.
Tabs, autosave and backups
Several documents stay open in tabs. Each is saved automatically and gets its own permanent backups and previous versions.
File formats
Opens and saves HTML, plain text, Markdown and its own .calmly format, imports Word .docx files and exports to .docx and PDF.
Typewriter sounds and themes
Optional typewriter sounds, smart punctuation, a customizable caret and five color themes, with an Open Dyslexic mode and right-to-left support.

ghostwriter

Live preview
Shows the Markdown document as HTML beside the editor, tuned to stay responsive on large documents. The HTML can be copied into a blog.
Focus Mode
Highlights the text around the cursor and fades the rest. It can be set to highlight the current line, sentence, paragraph or three lines.
Hemingway Mode
Disables the backspace and delete keys so that drafting cannot be interrupted by editing, in the manner of a typewriter.
Outline navigation
A sidebar outline jumps to any section of the document, in the editor and in the live preview, by mouse or with Ctrl+J and the arrow keys.
Document and session statistics
A live word count sits at the bottom of the window, and sidebar tabs show further statistics for the document and the current session.
Export through Markdown processors
Exports to other formats using Pandoc, MultiMarkdown or commonmark, and uses Pandoc to render equations with MathJax.
