- Mermaid diagrams (flowcharts, sequence, Gantt, ER, and more)
- KaTeX math typesetting (inline and block equations)
- Live split-pane preview with real-time rendering
- Export to PDF, HTML, and raw Markdown
- Progressive Web App (PWA) — installable and offline-capable

It requires no account, no login, no subscription. It is 100% free.
