Nox

About

Dark mode for every website — instant, intelligent, and beautiful.

  Nox is a smart theme controller that detects whether a site is already dark or light, then
  applies pixel-perfect inversion only when needed. No more double-inverting dark sites.

  Features:
  • One-click dark or light mode for any website
  • Smart detection — skips inversion if the site already matches your chosen theme
  • Per-site settings that persist across visits
  • Normal and high contrast modes
  • Images, videos, and iframes stay natural (not inverted)
  • Keyboard shortcut (Alt+D) for instant toggling
  • Lightweight — pure CSS filter, no heavy processing

  Works on every website. No configuration needed — just click and go.
