MarkText

MarkText is a free desktop Markdown editor for people who want formatting rendered as they write, with a way to switch back to source. It is strongest for technical and structured writing on a computer. Its range of Markdown features and document exports is useful, but it has no mobile apps or publishing workflow.

Overview

MarkText’s real-time rendering gives Markdown writers a document-like view without removing access to the underlying syntax: WYSIWYG preview and source-code mode serve different preferences, while focus and typewriter modes offer more controlled ways to work through a passage. Local file support suits writers who want to work with documents on their desktop rather than depend on a publishing service.

The project is free and open source under the MIT License, requires no account, and says it does not track users. Volunteers build it, and the project invites sponsorship on GitHub. That makes the cost and account burden minimal; readers who need a formal publishing workflow or a mobile companion should choose another tool.

Key features

MarkText goes beyond basic prose with tables, footnotes, code highlighting, KaTeX math, and YAML, TOML, and JSON front matter. Mermaid, Vega, and Vega-Lite cover diagrams and charts, making the editor a more compelling option for technical notes and structured documents than a plain text-focused Markdown tool. Its Markdown flavor is custom, so writers who rely on a particular standard should confirm that it suits their workflow.

Thirty-three built-in light and dark themes provide a range of starting points, and CSS customization gives users control beyond those presets. This is useful for writers who care about their editing environment, though the facts do not indicate shared or centrally managed theme settings.

Documents can be exported as PDF or self-contained HTML. Those formats make it practical to hand off a finished document, but MarkText has no publishing workflow, so users looking to publish directly from the editor will need another step or another product.

Pricing

The Free plan costs nothing and includes free and open-source software, no account, and no subscription. There is no free trial because there is no paid tier to trial. No seat or usage caps are specified for the plan. This is a straightforward fit for individual writers who want a desktop Markdown editor without recurring charges; users should not expect a paid support tier, as the project is volunteer-built and instead invites sponsorship through GitHub.

Platforms

MarkText is available for Linux, macOS, and Windows, with no mobile apps. The installation notes require macOS 11 or later and Windows 10 or 11; installers are provided for arm64 and x64 on both systems. Homebrew, Chocolatey, and Winget are also listed as installation options. The desktop coverage is broad, but writers who switch to a phone or tablet cannot continue in a MarkText mobile app.

Who it's for

MarkText is a good fit for desktop writers who prefer live-rendered Markdown, need technical document features such as math, diagrams, code highlighting, or front matter, and want local files with PDF or HTML export. Its free, account-free setup also suits people who want to avoid a subscription. It is a weaker choice for teams that need a specific Markdown standard, users who need to publish from the editor, and anyone who needs mobile editing.

Verdict

Choose MarkText if you want a free desktop Markdown workspace that combines live rendering with source access and useful support for technical documents. Its strongest reasons to choose it are the breadth of its Markdown features, local-file workflow, and PDF or self-contained HTML export. Look elsewhere if mobile editing or direct publishing is essential, or if your work depends on a specific Markdown standard.
