Edit Markdown files with live, editable drawio (```xml) and PlantUML (```plantuml) diagram previews. Fully offline. MD Diagram Editor turns Chrome into a fast, offline Markdown workspace with live diagram previews. Open or edit any Markdown file and see your diagrams render as you type. Fenced code blocks marked as xml (drawio) and plantuml are converted into real, editable diagrams right next to your text, so documentation, architecture notes, and design docs stay in one file. KEY FEATURES - Live Markdown preview that updates as you type - Editable drawio diagrams from xml code blocks(format should be ```xml + code + ```) - PlantUML rendering from plantuml code blocks (format should be ```plantuml + code + ``` ) - Fully offline: nothing is uploaded, no account needed, no server round trips - Clean, distraction-free split view of source and preview WHY IT IS USEFUL Diagrams usually live in a separate tool, which means exporting images and re-importing them every time something changes. MD Diagram Editor keeps the diagram source inside your Markdown, so the diagram is always in sync with the document and stays reviewable in version control. PRIVACY All editing and rendering happens locally in your browser. The extension does not collect, transmit, or sell any personal data.
