And the best is: Unlike many competitors, Zettlr never locks you in. Zettlr supports almost every conceivable way to create links and identify your files. In other words: No matter where you come from — all Zettelkästen are beautiful and supported by Zettlr. Out of the box.

Zettlr Your Reference Manager

Zettlr integrates well with reference managers such as Zotero, JabRef, or Juris-M. Simply load your library into Zettlr, and begin to cite. Zettlr strictly adheres to established standards and does not reinvent the wheel. Citations can be loaded using CSL-JSON or BibTex and the citation processor only uses Citation Style Language, the de-facto industry standard for citations. This enables you to use one of over 9,000 different styles from the official Zotero repository!

Tag Along

Twitter invented them and, since then, everybody adopted them: Hashtags! Zettlr goes one step further, not only allowing you to link and categorize your notes using tags, but using its tag-manager you can assign colors to tags to visualize your notes immediately!
