A native macOS editor that combines distraction-free writing with live preview, elegant themes, and the precision of a craftsman's tool.
❧
Built with SwiftUI and AppKit. No Electron, no web bloat. Feels like it belongs on your Mac.
A fast, extensible editing surface powered by CodeMirror 6 via WKWebView. Syntax highlighting that stays out of your way.
Split-pane or WYSIWYG — see your rendered Markdown side-by-side or inline. Themes that match your mood.
Inspired by Alphonse Mucha and the decorative arts movement. Writing should be beautiful, not just functional.
Quick access to every action. Open files, switch themes, run commands — all from the keyboard.
Render to HTML, PDF, or presentation slides. Share your words in the format your audience expects.
