A notch for Windows.

Nook is a small glass pill at the top of your screen. Hover it and it springs open into a grid of tools: a timer, clipboard history, a color picker, your phone. Move away and it folds back out of your way.

Nook takes its accent color from your wallpaper. Pick one: this page follows too.

Light enough to forget.

Nook only works while you’re using it. Folded away, it uses almost nothing, so your games, calls and battery don’t notice it’s there.

Less than a ticking clock in your taskbar.

Idle memory

Smaller than a single browser tab.

Plugins add new tools to the grid. Every listing is reviewed before it appears here, and each one runs on its own, so a broken plugin can’t take Nook down.
