Features

One thing, done right.

01

GitHub-style rendering

Markdown parsed with marked.js. Tables, fenced code blocks, task lists, blockquotes — rendered cleanly without a browser.

02

Automatic Dark Mode

Follows your system appearance. Or override it manually — Light, Dark, or System — persistent across sessions.

03

Native macOS

Built with SwiftUI and WKWebView. Open files, Recent Files, drag & drop, window management — it just works.

04

No Electron. No runtime.

Under 500 KB total. No bundled browser, no Node.js, no frameworks. Just a native binary that launches in under 50 ms.
