Markdown, side by side.
A lightweight Markdown editor for Windows 11: raw source on one side, a rendered pane you can type into on the other, in a native shell that opens instantly. No Electron, no bundled browser, no account.
Built for writing, not configuring
Everything you need to write and read Markdown, and deliberately nothing else.
Three view modes
Raw source with CodeMirror 6 highlighting, split view with synchronised scrolling, or a clean preview. Ctrl+E cycles them.
An editable rendered pane
The right side of Split is not a picture: type in it. Enter continues a list, Tab nests it, Ctrl+B and Ctrl+I toggle bold and italic, and task boxes are clickable. Tables and raw HTML stay byte-for-byte as raw blocks, and Ctrl+Alt+P flips the pane to a faithful read-only preview.
GFM rendering
Tables, task lists, footnotes, heading anchors and fenced code with language highlighting, rendered as you type.
Untrusted input, by default
Rendered HTML is sanitised with DOMPurify under a strict content security policy, remote images are blocked instead of fetched, and saves are atomic — temp file, flush, rename.
Tabs that remember
Dirty markers, middle-click close, and your whole session restored on relaunch. Ctrl+N reuses an untouched empty tab instead of stacking blanks.
Folder sidebar
A read-only tree of Markdown files that follows the document you are editing, with a breadcrumb bar that opens any folder above it.
Native Windows shell
A real Win32 menu bar with accelerators, native file dialogs, drag-and-drop, single instance and remembered window geometry.
Text zoom, print, export
Zoom the text from 60 % to 240 % without the chrome reflowing, and print straight to PDF with a print stylesheet.
No account, nothing uploaded
No telemetry, no sign-in, no sync. Files are read and written locally by a handful of Rust commands that validate extension, size and path first.
The ones you will actually use
Every command also exists in the menu and on the ribbon.

Installing
Download the MSI, run it, and Markdown Studio takes over as the handler for Markdown files.
What the installer does
Installs per-machine into Program Files, so it asks for elevation once.
It registers .md, .markdown, .mdown and
.mkd, adds an entry to Add or remove programs, and ships its full
third-party notices alongside the executable.
Windows 10 or 11 on x64. WebView2 is preinstalled on Windows 11 and already present on nearly every Windows 10 machine.
How it treats your files
Markdown is treated as untrusted input: rendered HTML is sanitised with DOMPurify under a strict content security policy, and remote images are blocked rather than silently fetched.
Saves are atomic — written to a temporary file, flushed, then renamed over the target — and files keep the BOM state and line endings they were opened with.
