Content-aware per-tab brightness adjustment. Auto-dims bright pages, leaves dark pages alone. Tired of blinding white pages late at night? DimWise intelligently analyzes each page's background color and automatically adjusts brightness — bright pages get dimmed, dark pages are left untouched. Unlike system-level brightness controls that affect your entire screen, DimWise works per-tab, so each website gets the right brightness without affecting anything else. Features: Content-aware auto mode — detects page luminance and dims bright pages automatically Manual mode — set a fixed brightness level with a simple slider Per-site custom settings — save different preferences for different websites Live preview — see brightness changes in real-time as you drag the slider Managed sites dashboard — view, manage, and remove all your custom site overrides in one place Adjustable strength — control how aggressively auto mode reduces brightness, from subtle to aggressive Dark mode detection — automatically re-adjusts when a site switches between light and dark themes Zero permissions abuse — no data collection, no network requests, everything stays local in your browser Lightweight — no frameworks, no dependencies, pure vanilla JS under 15KB total
