Dark mode for sites that never made one
Any page turns dark, including ones whose authors never considered it.
Dark Mode
Dark mode for sites that never built one
Any page turns dark, images keep their real colours, and sites that are already dark are left alone instead of being inverted twice.

Every tab is a vote for who you are becoming.
Dark, without the mess
Images keep their colours. Already-dark sites are left alone.

The rhythm runs itself; you stop watching the clock.
Warm after sunset
The page warms up in the evening instead of glowing at you.

click the toggle — this is the real interface, not a screenshot
Most dark modes invert everything, including the photographs. That is not a theme, that is a negative.
How it works
Switch it on and forget about it
The work is in what it does not touch.
01
It checks the site first
Pages that already ship a dark theme are skipped, so nothing gets inverted twice.
02
Colours are turned, not flipped
Text and backgrounds change. Photographs, videos and logos keep their original colours.
03
You tune it
Intensity, contrast and brightness, globally or for one site.
What you get
What makes it different
Already-dark sites are skipped
Detection runs before anything is changed, so dark sites are left as their authors made them.

Images stay honest
A photo of a sunset does not become a photo of a night sky.

Common cases
Where dark mode gets used
Reading at night without burning your eyes
Adjust brightness and contrast to the room rather than accepting one preset.
Keeping photos looking like photos
Images and video keep their original colours; only interface colours change.
Sites that are already dark
They are detected and left alone, so nothing gets inverted twice into an unreadable mess.
Dark mode only on some sites
Per-site rules let you keep it where it helps and off where it does not.
Dark after sunset, light by day
Scheduling comes with Pro, so you do not toggle it by hand.
What dark mode reads
It reads the colours of the page you are on to decide what to change, and that happens entirely inside your browser. The list of sites you gave rules to stays on your device.

About Dark Mode
Will it break sites that are already dark?
No. Detection runs first and such sites are left untouched — double inversion is exactly the bug this avoids.
Do images get inverted?
No. Images and video keep their original colours; only interface colours change.
Can I turn it on only for some sites?
Yes. You can run it everywhere, or keep a list of sites where it applies.
Is dark mode free?
Yes, on any site. Scheduling and per-site rules are part of Pro.
The other eleven
They work together, not instead of each other

It comes with blocking, focus sessions, screen time and eye care — free.
