Tintbox

Dark mode for anything. Dim, tint, invert or blur bright screen shares and pages with a movable, click-through box.

Someone shares a blinding white screen in your meeting. Dark mode can't touch it, because a shared screen is video, not a web page. Tintbox can. Drop a box over anything bright and it filters whatever is underneath: shared screens in Google Meet, Teams and Zoom on the web, white documents, harsh dashboards, any web page. The box is click-through, so you can keep using the page beneath it. FILTERS - Dim: lower brightness without changing colors - Amber and Rose: warm, low-blue tints for evenings and long calls - Gray: drain harsh colors from busy slides - Invert: turn white whiteboards and docs dark - Brighten: lift a share that's too dark to read - Blur: soften distracting or sensitive areas - Blackout: cover an area completely CONTROLS - Drag, resize and stack as many boxes as you need - Intensity and opacity sliders for each box - Inside / Outside: filter the box, or everything except the box to spotlight one area - Presets: Meeting, Slides, Whiteboard, Night, Brighten, Reading - One click to cover the shared screen in a call - Turn each box on or off, or all of them at once BUILT FOR CALLS - Hover a box to move it or open its settings - Keyboard shortcuts you can record yourself - "Always on for this site" brings your boxes back automatically - Works in full screen PRIVATE BY DESIGN - Runs only on tabs where you use it - Settings stay in your browser - Never reads, records or sends what's on your screen - No accounts, analytics or ads - The optional Feedback form sends only what you type, plus your browser version Tintbox is free. If it saves your eyes, you can support it on Ko-fi from the link in the popup.
