The open, cross-platform art platform

Art that
comes alive.

Paint on any device — iPad, iPhone, Android, Mac, Windows, web — and every stroke renders identically. Then share the performance, not a flat image, and meet other artists in a living museum.

The Museum

A museum where the paintings perform.

Browse the collection. Approach a frame and it wakes up — re-painting itself stroke for stroke, the way it was made. It’s a recorded performance, not a video, reproduced identically on every device.

Everywhere, identical

One painting. Every platform.

A brush stroke on an iPad renders pixel-for-pixel the same on Android, Windows, Mac, and the web — guaranteed by hash. That’s what makes true cross-platform collaboration possible.

OpenPaint

An open format.

Brushes and paintings live in an open, documented format that renders identically across a deterministic, bit-exact engine. Your work isn’t locked to one app on one device — it’s yours, portable, and reproducible.

Learn

Watch how it’s made.

Because every work keeps its full performance, you can slow it down, speed it up, and study exactly how an artist built it — tool by tool, stroke by stroke. The most transparent way to learn to paint.
