  • Resizable, collapsible Table of Contents with active-heading tracking
  • Syntax highlighting for ~35 languages via highlight.js
  • Mermaid diagrams (flowchart, sequence, class, state, ER, gantt, pie, journey, git graph, mindmap, quadrant)
  • KaTeX math rendering (inline $…$ and display $$…$$)
  • Adjustable reading width (full, wide, normal, narrow) and font size
  • Toggle rendered / raw with one click
  • XSS-safe: all output sanitized with DOMPurify
  • Works on local files (file://) and remote raw-file URLs
  
  PRIVACY
  All rendering happens locally in your browser. No data is sent to any server. No analytics, no telemetry, no remote code. Auto-reload (when enabled) only reads
   your local file — nothing leaves your browser.
