Here is the whole of Pintsei in one breath: a child picks a creature, colors it with their own imagination, and then — with one tap — watches it come to life and swim, fly, or float away into a living world. A sea turtle glides into a coral reef. A propeller plane lifts off into a cloud city. A little astronaut drifts among the stars.
It works on any device with a browser. There's nothing to download, no ads, and nothing to figure out: color, tap, alive. Children color on the screen with their fingers, or on printed paper that the camera scans back in.
And the entire experience rests on two small, made-up words — the two halves of our name, printed on the two purple buttons your child will press a hundred times: Pint and Sei.
A name made of two old ideas
Pintsei is two words holding hands.
The first half comes from the Spanish pinta — paint, a stroke of color. But in the Spanish tradition, pinta carries a second meaning that we love even more: a mark of character. The look of a thing that tells you who it is. When a child colors a sea turtle's shell in sunset orange because "that's how my turtle feels," that's not just paint. That's pinta.
The second half is the Japanese sei (生) — life, birth, and, beautifully, the raw and unfinished. A blank template is sei. A freshly colored creature, one breath away from moving, is sei. The moment it starts to swim — that's sei becoming true.
Pinta: the color that shows character. Sei: the life it wakes up into. Put them together and you get the whole journey of a Pintsei creature.
So in Pintsei, the words work exactly the way they sound. You Pint a creature when you color it. You Sei it when you bring it to life.
Two buttons, one journey
Every visit follows the same four little steps:
- Imagine. Pick a world — the Tropical Coral Reef, Sky City, or Cosmic Space — and choose a creature that lives there.
- Pint it. Pour your imagination into it. Crayons on paper or fingers on the screen — every stroke is your child deciding who this turtle, this helicopter, this little astronaut is going to be.
- Sei it. One tap, and the coloring takes its first breath. The creature enters its world and starts to swim, fly, or float — with your child's colors, in your child's style.
- Explore. Follow it. Where does a seahorse hide? Why does a jellyfish drift like that? Every seied creature is a doorway into its ecosystem.
You'll spot the words in little places, too. Every creature card counts how many times it has been Pinted and Seied by families around the world — we call them Pints and Seis, and yes, we know how fun that is to say out loud.
Why invented words are good for children
Here's the part we care about most, as the people building this for small humans.
Children are natural word collectors. Give a child a real, slightly odd word — metamorphosis, bioluminescence, sei — and they don't just learn it. They own it. It becomes a badge: a word grown-ups have to have explained to them, by the child.
That's exactly the feeling we want around creating. When your child says "I pinted a shark and then I seied it!" at dinner, three things are happening:
- Ownership. The activity has a name only they know. It belongs to them, the way a secret handshake does.
- A family word. Invented words become family vocabulary fast — "want to sei your drawing after bath?" — and shared language is how rituals form.
- A tiny lesson hiding inside. Sooner or later a curious child asks what the words come from. Then you get to tell them about a Spanish word for a painter's mark of character, and a Japanese character for life — and coloring time quietly becomes a small trip around the world.
A tiny glossary, for the fridge door
- Pint (verb) — to color a creature with your imagination. "I'm pinting my jellyfish purple and gold."
- Sei (verb) — to bring a pinted creature to life in its world. "Ready? Let's sei it!"
- Pints & Seis (nouns) — how many times a creature has been colored and brought to life, by everyone, everywhere.
So that's Pintsei, told from the very beginning: a place where coloring becomes a creature, a creature becomes a life, and seven letters from two corners of the world sit on two purple buttons — waiting for your child to press them.
