Features

One dark-mode toolkit for every site.

01

Fine-tune the look

Adjust brightness, contrast, saturation, warmth, dimming, and intensity without changing every site the same way.

02

Remember settings per site

Enable, exclude, or optimize individual domains while keeping separate visual preferences for the sites you use.

03

Automatic scheduling

Use fixed times, system-theme matching, or optional sunrise and sunset scheduling based on your location.

04

Custom CSS for power users

Add per-site CSS overrides when a website needs a precise fix beyond the built-in dark-mode transformations.
