Nook 0.1.0

The first release of Nook, the floating notch for Windows.

Install

Download Nook-Setup-0.1.0.exe below and run it. Windows 10 or 11, 64-bit; no admin rights needed.

The installer isn't code-signed yet, so SmartScreen may say "Windows protected your PC": click More info, then Run anyway.

Setup installs for the current user (all users is offered too), adds a Start menu entry, optionally a desktop shortcut and launch at sign-in, and registers nook:// links so plugins install from the website. Uninstall removes those and asks before deleting %APPDATA%\Nook.

Build plugins

Plugins are a folder with a plugin.toml and a program in any language. See the plugin guide, the examples, and the nook-plugin skill for Claude Code.
