About Tintbox
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
