About MonoSleep - Pre-Bedtime Grayscale
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.
