Marked 3 Launches: Major Update to macOS Markdown Preview Tool After 12 Years

Marked 3, a comprehensive markdown preview and export application for macOS, launched on May 27, 2026, marking the most significant update to the software in over a decade. The new version introduces numerous features designed to enhance markdown editing workflows, including advanced DOCX handling, new PDF export capabilities, EPUB export functionality, and a Speed Reading (RSVP) mode.

The update addresses several pain points identified by existing users. A notable improvement is the implementation of per-document style memory that persists across file moves and renames, using macOS bookmarks as the underlying mechanism. Users can now set CSS themes individually for each document rather than relying solely on global preferences, and the new Style Manager allows users to edit, generate, reorder, rename, and manage styles directly within the application. Style preferences can be anchored to documents through metadata in headers, HTML comments, YAML front matter, or MultiMarkdown syntax.

Marked 3 positions itself as a specialized preview and export tool rather than a full-featured markdown editor, deliberately maintaining focus on its core functionality. The application supports multiple output formats including HTML, PDF, DOCX, and EPUB, alongside integrated writing and analysis tools and a custom style builder. Product Hunt users received promotional pricing options to lock in introductory rates at launch.

The software appeals to both content writers and developers, with particular emphasis on long-form writing capabilities. Advanced DOCX integration has been highlighted as a significant workflow improvement for users who need to share markdown documents in industry-standard formats. The development discipline shown in avoiding scope creep into editor functionality distinguishes Marked 3 in a landscape where many minimal tools gradually evolve into full-featured editors.
