Markdown Studio Pro

A calm desktop Markdown editor built around focused writing, readable documents, and native platform behavior.

---

Markdown Studio Pro combines a native desktop shell with a writing-first Markdown editor. The Windows version uses WinUI 3 for the application chrome and WebView2 for the document editor, keeping file handling and platform behavior native while preserving a flexible editing surface.

Current distribution: Download Markdown Studio Pro v0.1.0 for Windows x64 (portable ZIP) or view the v0.1.0 release notes. A dedicated installer/MSIX is not published yet.

Windows highlights

• Native WinUI 3 shell with an Editorial Pro-style command surface
• Light and Dark themes with live settings preview
• Markdown, text, HTML export and print/PDF workflow
• White-paper print output even when the app is in Dark mode
• Improved print pagination for headings, tables, quotes and code blocks
• Clear save states: Saved, Unsaved and Saving...
• Auto-save support for already saved documents
• Open/recent-file workflows and optional last-document restore
• Window size and position persistence
• Drag & drop for .md, .markdown and .txt with a native drop surface
• Find & replace, source editing, command palette and Smart-Tab commands
• Focus mode, spellcheck, word goal and reading statistics
• Selection statistics for selected words and characters
• Configurable editor width, font size and line height with live preview

The existing keyboard, shortcut, Smart-Tab execution and editor key handling are intentionally preserved as part of the confirmed Windows baseline.

Platform status

Platform	Stack	Status
Windows	WinUI 3 + WebView2 + .NET 8	Active, current Editorial Pro/QoL track
macOS	SwiftUI + WKWebView	Separate source track; not changed by the Windows polish work

Build the Windows app

Requirements

• Windows 10 version 2004 / build 19041 or newer
• x64
• .NET 8 SDK
• Microsoft Edge WebView2 Runtime
• Visual Studio with Windows App SDK / WinUI tooling, if you prefer IDE builds

Helper scripts

From the windows directory:

build_winui3.bat
start_winui3.bat

The build script restores and builds the self-contained win-x64 app and checks that the executable, editor.html, and WebView2Loader.dll are present in the output.

Direct build

dotnet build .\windows\MarkdownStudioPro.WinUI\MarkdownStudioPro.WinUI.csproj -c Debug -r win-x64

More details are in windows/README_WINUI3.md.

User-facing release notes are tracked in CHANGELOG.md. Detailed Windows implementation notes live in windows/PATCH_NOTES.md.

Development notes

AI.md records project decisions, completed stages, compatibility constraints, and the confirmed baseline for future work.

Windows should follow the product direction without replacing native Windows behavior with macOS-specific interaction patterns. Changes to established keyboard or editor key handling should only be made deliberately and tested separately.
