• RTF → MD mode (default): Paste anywhere on the page (⌘V/Ctrl+V) — rich content loads in the editor above, Markdown updates live below. Edit the rich text freely; Markdown follows. Click Markdown to select all, then ⌘C to copy.
  • MD → HTML mode: Edit Markdown directly in the top pane. The bottom pane shows a live HTML preview. Supports math via $...$ (inline) and $$...$$ (block), and syntax highlighting in fenced code blocks (e.g. ```python).
  • Switch modes with the RTF→MD / MD→HTML segmented button. Switching back to RTF→MD loads the current Markdown into the rich text editor.
