Paintbox 95: a retro paint program with an AI that paints with you

Paintbox 95 is a free retro paint program in your browser. Draw with pixel tools and loud flat colors, or type an idea and watch Claude paint it stroke by stroke. Save a PNG or share it to the gallery.

Paintbox 95 brings back the simple paint program that came with every computer in the 1990s: jagged pixels, a 28 color palette, the airbrush and the fill bucket. Type an idea and Claude, the AI made by Anthropic, plans the picture and paints it with the same tools, one stroke at a time.

Welcome to Paintbox

Remember when every computer came with a tiny art studio?

Before layers, filters and a thousand brush presets, there was Paint. A bucket that flooded the whole screen because you missed one pixel. An airbrush that made you feel like a graffiti legend. Stick figures, wobbly suns and your name in rainbow letters.

It's all back, jagged edges included. No undo anxiety though: Ctrl+Z works this time.
