Automated bedtime grayscale filter to reduce late-night screen stimulation and encourage healthy sleep habits. MonoSleep is a minimalist, local-first bedtime monochrome filter extension designed to suppress dopamine stimulation from late-night screen time and help you build healthier sleep habits. Similar to mobile Bedtime / Sleep Mode, removing vibrant colors makes video thumbnails, social media feeds, and infinite scrolling naturally unappealing, making it easier to log off and rest. 🌙 Key Features: • Scheduled Bedtime Grayscale: Automatically transforms all web pages to 100% grayscale during your designated sleep hours (e.g. 23:00 to 07:00). • Midnight Rollover Support: Seamlessly handles overnight time ranges spanning across midnight. • Subtle Pre-Bedtime HUD: Injects a discreet, Shadow DOM-isolated countdown reminder 15 minutes before your scheduled bedtime. • Instant Whitelist: Keep productivity or reference tools in color with single-click domain exclusion. • 1-Hour Snooze: Temporarily restore full color when you need to finish an urgent late-night task. 🔒 100% Local & Privacy-First: • Zero external network calls or tracking scripts. • 100% Vanilla JavaScript & CSS. Ultra-lightweight package • Zero telemetry. All configuration stays strictly inside your local browser storage.
