What Makes It Different

Damson is written in Swift with Metal and CoreText, targeting exactly one platform. That single decision is what lets it do the things below — none of which require a setting to turn on. They’re just how the app behaves.

The short version

• Scrolling feels like a Mac. ProMotion 120 Hz, per-pixel scrolling, momentum and rubber-banding — the same feel as scrolling a web page in Safari.
• Korean input just works. Type as fast as you like; the first jamo never disappears and compositions never tangle. We tracked down the subtle timing races in the macOS Korean IME and fixed them, and in-progress compositions render right where they belong.
• The GPU draws everything. The Metal renderer handles truecolor, bold/underline/strikethrough/hyperlinks, double-width CJK, and color emoji (including ZWJ sequences and flags). Symbols your font lacks — like ④ — still show up through font fallback.
• The fundamentals of an all-day tool. Tabs and split panes (split, rearrange, switch), a settings UI, session restore that brings everything back when you relaunch, Sparkle auto-updates, and a damson-cli for scripted control.
