“Echo should feel like a well-made object that lives in the background until it is needed. When it appears, it should immediately communicate state, reduce friction, and leave a strong product impression.”

/ Native in behavior

Respects macOS conventions — system typography, keyboard shortcuts, window management, light and dark mode.

/ Distinctive in presence

The floating capsule is unmistakably Echo. A sculpted silhouette that earns its place on your screen.

/ Sculpted, not generic

Every surface, radius, and shadow is deliberate. Form over color. Premium without being busy.

/ Quiet, then confident

Invisible until needed. Alive when listening. Confident when delivering results. Never noisy.
