The intelligent, flicker-free screen dimmer and circadian eye protection tool designed specifically for Google Chrome. Available now on the Chrome Web Store.
Smooth multi-layer dimming overlay calibrated in linear perceptual space. Dims every web page cleanly down to 10% without washed-out grays.
Dynamically matches color temperature to natural astronomical daylight cycles. Warms your screen automatically at sunset to reduce blue-light strain.
Crushes dark background grays to true #000000 on OLED displays, turning off pixels completely to maximize contrast and battery efficiency.
Intelligently keeps HTML5 and YouTube videos bright and vivid while softly dimming surrounding sidebars, comments, and navigation bars.
Allows keeping physical monitor backlights at 100% to eliminate high-frequency PWM flicker while dimming via optical software multiplication.
All core dimming features operate completely offline inside your browser. No telemetry, no analytics, and zero browsing data collected.
Smart Brightness adheres strictly to the Google Chrome Web Store Minimal Permissions and Single Purpose policies. The extension processes all page styles locally in memory. We never sell, transmit, or log your browsing history or personal data.
