Monochromate
Greyscale browser extension to reduce distractions and screen time
Monochromate Overview
Monochromate is a free browser extension designed to help users reduce screen time and combat doomscrolling by converting websites to greyscale. By removing colors from web pages, it decreases visual stimulation that triggers dopamine responses, making browsing sessions less addictive. The tool works by modifying webpage CSS in real-time while preserving all functionality. It's particularly useful for people looking to minimize digital distractions, improve focus, or break compulsive browsing habits. Monochromate is completely open-source and privacy-focused, storing all settings locally without tracking user activity. Available for both Chrome and Firefox browsers, it offers customizable intensity controls and smart site exclusion features for when color is necessary.
