Dimmer: Grayscale Focus Extension

Make distracting sites gray and harder to open. A grayscale focus extension and focus blocker with an accountability partner.

Dimmer is a free grayscale focus extension for Chrome that makes distracting websites boring instead of just blocking them. Turn Instagram, YouTube, TikTok, Reddit, Facebook and any site black and white, add a pause before you open them, and let a friend keep you honest. Most focus blockers fail for one reason: you switch them off the moment you're tempted. Dimmer takes a different route, built on habit science. It makes distractions less visible, less attractive and harder to reach, so staying off them takes less willpower. ✨ WHAT YOU GET, FREE 🎨 Grayscale mode: turns any site black and white, so the colour that keeps you scrolling disappears ⏳ A pause before you enter: a short countdown with a big "back to what I was doing" button that takes you straight to your previous page 🙈 Hidden feeds: removes recommendation feeds on popular sites and distracting results from Google Search ⏱️ Time badge: a small counter showing how long you've spent on a site today 🌐 Works on any site: popular sites are ready out of the box, and you can add any other website in one tap 🤝 Accountability partner: invite a friend who gets a weekly summary and a gentle heads-up if Dimmer goes quiet 🎯 BUILT FOR Students studying on a laptop, people working from home, and anyone trying to stop doomscrolling or cut their screen time without blocking the internet entirely. Dimmer runs in desktop Chrome, which makes it a good fit for study sessions and work hours. 🔒 PRIVACY FIRST Your browsing stays on your computer. Dimmer never sends the sites you visit, page addresses or page titles anywhere. An account is only needed for the accountability partner. If you make one, we store your email, your partner's name and email, and daily totals like "went back 6 times", never which sites. No ads, no selling data. 🧩 YOU CHOOSE THE SITES Dimmer only works on the sites you pick: a short default list, plus any you add yourself, one at a time. 🚀 COMING WITH PRO (NOT AVAILABLE YET) Slow video playback, heavy scrolling, half-screen mode, waits that grow each time you come back, reminders that appear mid-scroll, quiet tabs, a habit contract and unlimited gated sites. Pro is coming soon, and the free version above is complete on its own. 🧪 BETA Dimmer is in beta, built by an independent maker. Found a bug or have an idea?
