Features

One extension.
Every site, dark.

Built for people who spend hours in the browser and need their eyes to last longer.

Automatic dark theme
Converts any website to dark mode the moment you visit — no manual toggling site by site.
Brightness & contrast controls
Fine-tune brightness, contrast, sepia, and grayscale with per-site sliders — saved automatically.
Per-site custom settings
Apply unique theme settings to individual sites. Override the global theme for specific domains you use daily.
Site list — whitelist & blacklist
Enable dark mode only for listed sites, or disable it for sites that already have their own dark theme.
Scheduled automation
Enable dark mode on a time schedule, by sunset/sunrise at your location, or follow your system colour scheme.
Multiple generation modes
Choose Dynamic, Filter, Filter+, or Static theme generation — each adapts differently to complex page layouts.
