// how it works

How it works

  1. Install Zettlr

    Download the installer for Windows, macOS or Linux from zettlr.com — free, no account.

  2. Connect your references

    Point Zettlr at your Zotero library (or another CSL database) in settings, so citations autocomplete as you type.

  3. Write and export

    Write in Markdown in a project folder, then export through the built-in Pandoc pipeline to PDF (via LaTeX), DOCX, HTML or slides with your template.

Why people love it

Citations done right

Deep Zotero/CSL integration: cite as you write, with the bibliography generated on export — the feature academic writers actually need.

Serious export pipeline

Pandoc + LaTeX templates turn Markdown into journal-ready PDFs, Word documents and presentations.

Zettelkasten built in

Note IDs, tags and linking make the same app a thinking tool, not just a typewriter.

Writer-focused tooling

Distraction-free mode, word targets, readability stats, a table editor and a Pomodoro timer — no plugin hunt required.

Questions, answered

Who makes Zettlr?

Hendrik Erz and the Zettlr community (Zettlr/Zettlr on GitHub); development is funded by donations, not by locking features.

Is Zettlr free?

Yes — GPL-3.0 licensed, all features included, no premium tier.

Do I need Zotero?

No, but the pairing is the point for academics: any CSL-compatible database works, and Zettlr can also manage without one for non-academic writing.

How does it compare to a well-known alternative?

Against Scrivener, Zettlr is free, Markdown-native and far stronger on citations and academic export; Scrivener counters with its corkboard and compile system for fiction. Against a plain Markdown editor, Zettlr adds the whole publication pipeline most editors leave to you.

How do I get started?

Install from zettlr.com, open a folder as a workspace, connect Zotero if you use it, and export your first document to PDF.
