I recently tested Zettlr, a Markdown editor built for writers and researchers like me. Here is my detailed review based on practical usage and research: Zettlr shines with its clean, distraction-free interface perfect for long writing sessions. I loved the seamless Zotero integration for citations, making academic work a breeze, and Pandoc exports to PDF, Word, or HTML in seconds. The Zettelkasten support and full-text search helped me link notes effortlessly across projects. It runs offline on Windows, Mac, and Linux with customizable themes, including dark mode. Stats like word count and Pomodoro timer kept me productive. Setup was quick, and the interactive tutorial guided me perfectly. My only gripe: no mobile app limits on-the-go edits, though files stay portable in plain Markdown. Overall, Zettlr transformed my workflow. Free, open-source, and powerful, it's ideal for serious writers seeking focus without lock-in. Highly recommend trying it.
