About Zettlr

Zettlr is a desktop writing application described on its site as a one-stop publication workbench. It runs on Windows, macOS and Linux and is designed to support a writing project from early notes through a journal submission or a finished book manuscript. Files stay on your computer; the site says there is no forced cloud synchronization and no telemetry, and even the update check can be turned off.

The editor lets you decide how much formatting you see, so it can behave closer to plain text or closer to rich text. LaTeX math and Mermaid charts are rendered in the document, and an extensive set of settings plus custom CSS can be used to change the interface. Zotero, JabRef and Juris-M can be connected for citations, with over 9,000 citation styles available.

For publishing, a profile system built on Pandoc exports a document using a chosen template, which the site presents as a way to submit to journals and conferences; presentation profiles for Beamer, reveal.js and PowerPoint are also described. It suits researchers, academics, journalists and students who write long, source-heavy documents and want their files kept locally.
