Keep it editable.
zd md gives Markdown the measure, focus, and calm of a reading surface—without splitting your work between a preview and an editor.
Available for macOS and Windows · local files by default
The document is the interface
One surface for reading and writing.
Attention, directed
Focus a line, paragraph, or section while the shape of the surrounding document remains.
Local by default
Open ordinary Markdown files and folders. Remote images stay unfetched unless you ask.
Built for real repositories
The folder stays visible. The document gets the room.
Work across Markdown files in stable path order, save safely, and notice external changes without handing the app more filesystem access than the workspace needs.
