About PlainMark Editor
PlainMark Editor is a native Markdown editor for Mac, iPhone, and iPad. It lets writers create and edit standard Markdown files in either a source view with syntax highlighting and line numbers or a formatted view, while keeping the same document and selection in place when switching views. Formatting controls support headings, bold and italic text, links, lists, block quotes, and code. Users can open and save .md files, work offline with documents stored on their devices, and export to paginated PDF, PNG, DOCX on Mac, HTML, RTF, plain text, or Markdown. The app is designed for notes, drafts, articles, documentation, and README files without an account, cloud service, or subscription. It is available as a one-time purchase across Mac, iPhone, and iPad.
