Screen Dimmer & Reading Spotlight

Black out the rest of the screen except what you want to read or see. Focus elements, draw spotlight box, or reading ruler.

Eliminate distractions, reduce eyestrain, and restore deep focus. Screen Dimmer blacks out the surrounding page in pure tranquil darkness, keeping only your selected article, paragraph, image, or video illuminated. 🎯 3 INTUITIVE FOCUS MODES: 1. Element Focus: Click any paragraph, article card, graphic, or video to instantly shroud everything else in black. As you scroll, the spotlight automatically follows your reading target! 2. Draw Custom Box: Click and drag anywhere on screen to frame an exact region with a crystal-clear spotlight. 3. Reading Ruler: A floating spotlight band that glides down the page with your mouse for line-by-line reading without losing your place. ✨ FEATURES: • Adjustable Darkness: Dim from 40% soft shade all the way to 100% pitch black. • Background Blur: Optionally blur peripheral animations, flashing ads, and sidebars for complete calm. • Native Interactivity: You can still highlight text, copy code, click links, and scroll inside the illuminated area with zero lag. • Zero Page Conflict: Built with an isolated Shadow DOM so host site stylesheets never interfere with controls. • Draggable Floating HUD: Quick controls right where you need them, or minimize to a tiny floating dot. • Instant Exit: Press Escape anytime or click outside to return to normal. 🔒 PRIVACY FIRST: • 100% offline and client-side. • No analytics, no tracking, no external network requests. • Your preferences are saved locally on your device via chrome.storage.
