Zettlr

Zettlr provides a markdown‑based authoring environment that guides users from initial note‑taking through to final manuscript or journal submission. It combines a plain‑text editor with features such as citation handling, project organization, and template‑driven typesetting, allowing researchers, journalists, and writers to keep all stages of a publication workflow within a single application.

The program emphasizes privacy and local file storage, offering no mandatory cloud sync or telemetry. Users can link and visualize notes, perform fast searches, and generate outlines automatically from marked sections, supporting a Zettelkasten‑style workflow. Integration with external reference managers supplies on‑demand bibliography data.

Available for Windows, macOS, and Linux, Zettlr is free and open source, maintained by a community of contributors. Its design focuses on speed, efficiency, and flexibility, aiming to reduce the administrative overhead of writing and publishing.
