Rendering

Code highlighting, math, diagrams, alerts, footnotes — all bundled, all offline.

The polished pane renders GitHub-flavored markdown plus the extensions developers actually use:

• Code blocks with syntax highlighting, in light and dark themes.
• Math — LaTeX-style $inline$ and $$block$$.
• Diagrams — fenced ```mermaid blocks render to SVG.
• GitHub-style alerts — > [!NOTE], > [!TIP], > [!WARNING], > [!CAUTION], > [!IMPORTANT].
• Footnotes — [^1] syntax with back-links.
• Tables, task lists, strikethrough, autolinks, images with titles.

Everything the renderer needs ships inside the app. It makes zero network requests — documents render identically on a plane.

Presentation mode

⌘⌥P turns the current document into slides — headings become slide boundaries. Useful for design docs and standups without leaving the editor.

Export

• PDF (⌘E) — rendered through the same engine as the polished pane.
• HTML — a single self-contained file with CSS baked in.
• Copy as HTML — the rendered article straight onto the clipboard.
• Print (⌘P) — the standard macOS print panel.
