On the surface, Dendron may seem like a simple Markdown extension, but it can serve as a full-fledged Personal Knowledge Management system. If you prefer adding visual diagrams to your notes as much as I do, you’ll be glad to know that Dendron supports Mermaid diagrams. Likewise, it’s compatible with the KaTeX typesetting library, which makes adding properly-formatted math functions a piece of cake, and I can separate conventional notes from my programming snippets via code blocks.
I also adore the reference facility in Dendron, as it lets me paste snippets (or even entire notes) from other .md files into a document. Alternatively, I can add backlinks within my notes to navigate between them with ease, while the customizable schemas are a godsend when I want to create common templates and save time that I’d otherwise spend adding the same elements in every .md document. The best part? It supports note refactoring, meaning all the documents referencing a specific text snippet will automatically update their backlinks if I end up modifying the original .md file.
