Education is freedom.
Make it free.

AI changes the cost of teaching. We use it to give every person a great teacher, wherever they learn, for life.

A short film across the places we learn: a girl biking to school at sunrise, a father and son at the kitchen table, a classroom, a campus, a welder, nurses after a night shift, a mother home from work, friends jumping into a lake, a graduation, and a family with sparklers at dusk.

Why now

For most of history, the best education in the world was a private tutor. It was the privilege of a few. AI changes the cost of teaching, and with it, who gets to learn. Now every person can have a tutor of their own, in every place they learn.

$0
The cost to start learning. For everyone, everywhere.
1B
One billion people with a great teacher by 2035. Then everyone.
IIIWhat we build

Built once.
Brought to everyone.

A firefighter on a base and a girl in a refugee camp learn in very different places, on tools that share one engine. We build the hard parts once, open them wherever we can, and bring them to every place people learn.
