What paintBrush is
paintBrush is a cozy, distraction-free digital coloring book designed for children and families. Opening in a new browser tab with one click on the toolbar icon, it offers 150 offline illustrations spanning three distinct developmental age tiers. Kids simply pick a book, select a crayon, and tap to fill shapes without any frustrating slips or messy borders.
Built with privacy and safety as first principles, paintBrush operates 100% offline. It never loads advertisements, has zero telemetry or analytics beacons, requires no accounts or logins, and never transmits data outside your computer.
