Ghostwriter

Ghostwriter is a free, open-source desktop editor for people who write in Markdown and keep their files locally. It suits focused solo drafting better than collaboration, and its strongest case is a disciplined writing workspace with unusually flexible preview and export tools. Linux and Windows are the practical choices; macOS setup demands technical effort.

Overview

Ghostwriter stays deliberately narrow: a distraction-free editor for GitHub-flavored Markdown, not a general document suite or online team workspace. It opens local files and renders a live HTML preview, which you can copy as HTML or send through export tools for reuse in other publishing workflows.

The software is free and open source under the GNU General Public License v3.0. There is no subscription or trial decision to make, though installation convenience depends heavily on your operating system.

Key features

Focus and writing controls

Focus Mode dims everything except text around the cursor. You can set its scope to a line, sentence, paragraph, or three lines, so it works for either tight editing or a slightly wider view. Full-screen mode removes more interface chrome. Hemingway Mode goes further by disabling backspace and delete while you write: a useful constraint for an uninterrupted first draft, but unsuitable if you routinely revise mid-sentence.

Light and dark themes are included, and custom themes are supported. That gives appearance-conscious writers more control than a fixed editor, without turning Ghostwriter into a heavily configurable workbench.

Preview, processing, and export

The HTML preview updates as you write and can be copied directly. Ghostwriter includes the cmark-gfm processor and can use Pandoc, MultiMarkdown, Discount, or cmark when those tools are installed. Export routes cover HTML, Pandoc, MultiMarkdown, and commonmark, giving technically minded users several ways to move a draft into another format. The trade-off is that some processor choices depend on separate software being present, so the broadest workflow is not entirely self-contained.

Statistics and file safety

Live word count, document statistics, and session statistics make it easier to track both a manuscript and an individual writing period. A document outline provides quick navigation in structured files. Autosave and file-backup options add protection for local work, an important advantage for writers who do not want their drafts tied to an online account.

Pricing

There are no paid tiers, seat charges, usage quotas, renewal terms, or free-trial expiry to manage. The free plan is therefore the complete product rather than a restricted entry level, and it fits anyone who accepts a desktop, local-file workflow.

Platforms

Linux users get repository and installation guidance for Ubuntu, Fedora, and Arch Linux. Windows 10 has a portable 64-bit version, which is convenient when you want to run the editor without a conventional installation. macOS support is unofficial and community-provided; there is no installer, so users must compile the source. That requirement makes Ghostwriter a poor recommendation for Mac users seeking a ready-to-run app.

Who it's for

Choose Ghostwriter for focused Markdown drafting, local-file ownership, and detailed control over preview, processors, and exports. It is especially suitable for writers, developers, and documentation authors who value word/session statistics and an outline alongside a restrained interface. Look elsewhere if you need browser-based collaboration, shared editing, or a simple macOS installer.

Pros and cons

• Pros: Focus Mode, full-screen writing, and an optional Hemingway constraint support deliberate drafting.
• Pros: Live HTML preview, multiple processor integrations, and four export targets accommodate varied Markdown pipelines.
• Pros: Statistics, outline navigation, autosave, and backups strengthen long-form local writing.
• Cons: macOS users must compile community-supported source because no installer is provided.
• Cons: Pandoc, MultiMarkdown, Discount, and cmark workflows require those processors to be installed separately.
• Cons: Its local desktop focus offers no built-in web collaboration workspace.

Alternatives

Browse Markdown editors for a wider comparison. Choose StackEdit instead if you want a free, open-source web editor. PanWriter is another free, open-source option across Linux, macOS, and Windows. Pick HackMD when web collaboration and a free team allowance matter more than a purely local workflow. MarkText offers a free, open-source, no-account desktop alternative. HedgeDoc suits users seeking a self-hosted or web option. Dillinger is a no-signup web editor with no stated usage limits. Zettlr is a free, open-source cross-platform desktop choice. Muesli is a free, open-source service spanning web, API, self-hosted, and desktop platforms.

Verdict

Ghostwriter is a strong pick for solo Markdown writers who want distraction controls, measurable writing sessions, local files, and flexible export without paying. Its main reason to look elsewhere is platform friction: macOS requires compiling the source, and collaborative or browser-first work belongs in another tool.
