Live Preview or WYSIWYG Rendering
Modern editors offer varying approaches to how Markdown is displayed. Some, like Typora, offer a seamless experience where the Markdown syntax disappears immediately upon typing, showing you the final formatted result. Others use a split-pane view, where raw code exists on one side and the rendered output on the other. Deciding which workflow suits your cognitive style is a critical first step.
Knowledge Graph and Linking
For power users, tools like Obsidian have popularized the concept of "Personal Knowledge Management." These apps feature bidirectional linking, allowing you to connect notes to one another. Features like a visual graph view help you see the relationships between your ideas, which is invaluable for long-term projects and research.
Cross-Platform Synchronization
If you split your time between a desktop computer and a mobile device, synchronization is essential. Apps like Bear and Ulysses rely on proprietary cloud systems to ensure your writing is available everywhere. Other editors, such as Visual Studio Code, allow you to manage your files locally, giving you the flexibility to sync them via services like iCloud, Dropbox, or Git.
Export Flexibility
While the goal of Markdown is to remain in plain text, you will eventually need to share your work. Look for editors that provide robust export options, allowing you to convert your Markdown files into PDF, HTML, Word (DOCX), or EPUB formats without losing your structural hierarchy.
