Zettlr

Zettlr is a specialized note-taking app designed for academics, researchers, and writers. It is built around the Zettelkasten method and provides deep integration with citation managers like Zotero. It is open-source and uses local Markdown files, making it a great choice for those who need a robust, privacy-focused tool for academic writing. While it is not as user-friendly as Notion or Obsidian, its specific features for managing citations and academic workflows make it an invaluable tool for students and researchers who need to produce high-quality, cited work.
