A calm Markdown editor for writing, previewing, and managing drafts inside a disciplined Windows interface.

Sermon is a Windows Markdown editor built with WPF and .NET 10. It favors clear grids, black-white-gray hierarchy, red structural emphasis, low-decoration controls, and readable typography for technical documents, blog drafts, sermon notes, and daily writing.

01 / Writing modes

Edit, preview, and split modes support different phases of Markdown writing.

Sermon provides focused editing with syntax highlighting, realtime HTML preview, and a split mode that keeps the source and rendered document visible together. Preview refresh is debounced to reduce repeated rendering while typing.

02 / File workflow

The editor treats document management as part of the writing surface.

New, open, save, save as, folder browsing, tree navigation, multi-tab editing, unsaved-state indicators, and two-minute autosave create a practical local writing workflow instead of a single-buffer text box.

03 / Desktop architecture

WPF, AvalonEdit, Markdig, and WebView2 split the editor into reliable desktop responsibilities.

AvalonEdit handles text editing and Markdown syntax color, Markdig converts Markdown into HTML, WebView2 renders the preview, MahApps.Metro supplies the window frame and Material icons, and RelayCommand keeps toolbar and shortcut actions bound to UI state.
