Zettlr is a desktop application for writing and publishing that combines markdown editing with integrated export capabilities.
The tool addresses the workflow of writers, researchers, and academics who need to move seamlessly from drafting to publication. It centers on markdown as the primary format while providing tight integration with reference managers like Zotero and JabRef for citation handling. The application uses Pandoc, LaTeX, and Textbundle to enable export to multiple formats including Word documents and PDFs. It supports knowledge management through Zettelkasten methodology and includes full-text search across your notes. The privacy-first design keeps all notes stored locally rather than in the cloud.
Zettlr suits anyone working on long-form writing projects—dissertations, research papers, books—who wants to avoid vendor lock-in and maintain control over their source files. It works well for users already comfortable with markdown and those who need flexible export options to match institutional requirements. The application runs on Windows, macOS, and Linux as a native desktop tool, making it suitable for offline work. Choose it if you value privacy, want to avoid subscription services, and need professional export capabilities without leaving your editor.
The project maintains active development with passing unit tests and linting checks. The codebase is written in TypeScript and built on Electron and Node.js, indicating a mature technical foundation. Community engagement happens through a dedicated forum and Discord server, suggesting responsive maintainers and an established user base.
