Smart Brightness — Screen Dimmer & Eye Care

Intelligent, content-aware screen dimming and circadian eye protection.

Smart Brightness removes the glare from bright web pages without the washed-out, broken look of a naive dark-mode filter. It works out how bright each surface actually is, dims only what is blinding, and compensates the text contrast back up so nothing becomes harder to read. Everything runs locally on your machine. No page content, no browsing history and no analytics ever leave your browser. FREE — forever, no account • Brightness control, 0–100 %, applied before the first paint so navigation never flashes white • Colour temperature from 1800 K to 6500 K, with one-click presets • Adaptive contrast restoration, so dimmed text stays readable (WCAG AA) • Brand-colour fidelity — logos and call-to-action colours stay true • Images, video, canvas and WebGL are left untouched • "Ignore this site" for any domain you want the extension to stay out of • Keyboard shortcuts: Alt+Shift+D to toggle, Alt+Shift+Up/Down to adjust PREMIUM — the automation layer • Circadian automation — warmth and dimming ramp up on your own evening schedule, with separate night brightness and night colour temperature • Per-site brightness — a different level for every domain, remembered • OLED pure black — crushes bright backgrounds to true black so OLED pixels switch off entirely • Video spotlight — a playing video keeps full brightness while the page around it dims • Image hover reveal — lift any large image back to full clarity on hover • PWM flicker shield — removes brightness ramps for flicker-sensitive eyes • Alt + scroll wheel scrubbing — adjust brightness without opening the popup 7-day free trial, no card required.
