Duskmode – Dark Mode

Reliable dark mode for Google Docs, Sheets, Slides, Drive, Gmail, and any website. Easy on the eyes, day or night.

Duskmode adds a clean, reliable dark mode to any website — including the ones most dark-mode extensions get wrong, like Google Docs, Sheets, Slides, Drive, and Gmail. It's easy on your eyes during late nights and bright offices alike. Instead of maintaining fragile per-site styles, Duskmode intelligently inverts each page and corrects the colors so text is readable and real photos and video still look natural. It's fast and light — one CSS filter, no per-page style analysis, no CPU drain or page-load lag. And new in 1.3: sites that already ship a dark theme are detected and left alone, instead of being flipped back to light. Features • One global toggle, plus a per-site override for the page you're on • Keyboard shortcut to toggle: Alt+Shift+D (rebindable) • Skips sites that already have a dark theme — force it per-site if you prefer • Follow your system's light/dark theme, or set a time schedule • Four tint themes: Midnight, Slate, Forest, and Dusk • Brightness, Contrast, and Warmth sliders to fine-tune the look • Site Overrides list — review and remove every per-site choice • Toolbar badge shows the current state at a glance • Settings sync between your devices via your browser profile • Works on Google Docs, Sheets, Slides, Drive, and Gmail • Fast and private: no account, no tracking, zero network requests • Fully self-contained — no third-party code, fonts, or images Honest limits Browsers never allow extensions on chrome:// pages, the Web Store, or the built-in PDF viewer — no dark-mode extension can darken those (the popup tells you when you're on such a page). Media inside embedded frames can occasionally appear inverted; that's the trade-off that keeps embedded frames dark at all. Privacy Duskmode collects no data and makes no network requests. All your settings stay on your device; syncing between your own devices happens only through your browser's built-in sync.
