F3 for split-screen. - Live refresh: save in any editor, it re-renders in place - Tabs + outline that tracks your reading position - 9 themes + dark mode, one right-click to switch - Mermaid & KaTeX render natively - Export to PDF and single-file HTML 100% local: no account, no ads, no cloud. Ever.
