ThiefMD is an open-source Markdown and Fountain editor that also works as a file manager. Inspired by Ulysses, it focuses on organizing, previewing, compiling, and exporting large Markdown projects. It is more of a local writing tool than a typical cloud SaaS product; the text explicitly states that βYour library is your file system,β meaning the userβs own file system serves as the content library.
Its core features are built around the writing workflow: Markdown/Fountain syntax support, folder and file management, live preview, full-screen editing, focus mode, typewriter scrolling, library-wide search, writing statistics, and theme customization. Import and export are major strengths. Powered by Pandoc under the hood, it can export to PDF, ePub, docx, LaTeX, and more, and can also convert DocX, Odt, HTML, ePub, and other formats into Markdown. For bloggers and technical writers, it supports publishing connections for Ghost, WordPress, Medium, Forem, and WriteFreely, YAML Frontmatter for static site workflows such as Jekyll/Hugo, and integrations such as highlight.js, KaTeX, and BibTeX.
The captured text does not provide any commercial plans or pricing. It only states that ThiefMD is Open Source and provides GitHub and download links, so it appears to be primarily distributed as an open-source download. In terms of deployment, it is a desktop/local application. The text repeatedly mentions environments such as Linux, Flatpak, Ubuntu, and Fedora; there is no indication of cloud hosting, enterprise tenants, or a self-hosted server edition.
Its strengths include being open source, giving users control over local files, and being friendly to long-form project management. It is especially suitable for novels, academic papers, blogs, screenplays, and other work that requires chapter-based organization and delivery in multiple formats. Live preview, Focus Mode, Write-Good, spell/grammar checking, and the theme system improve the writing experience. The limitations are also clear: the text explicitly states that there is no built-in sync support and no built-in Git support. Common SaaS or enterprise software features such as team collaboration, permissions, audit logs, security compliance, SLAs, and enterprise support are not shown.
ThiefMD is suitable for individual writers, open-source enthusiasts, Markdown bloggers, academic writers, and content creators who need PDF/ePub/docx/LaTeX output. It is not a good fit as an enterprise knowledge base or multi-user collaborative documentation platform. The text does not provide information about access from China, so this cannot be assessed. Payment methods are also not disclosed. Possible alternatives include Typora, Obsidian, MarkText, Zettlr, Ulysses, or a VS Code Markdown workflow.
