Our mission at Ello is simple and urgent:
Maximize the potential of every child, everywhere.

We’re building the world’s first AI teacher to close that gap: one that listens, speaks, adapts, and inspires, just like the best human educators.

Our first product, Read with Ello, is already helping tens of thousands of kids each week learn to read. It listens as they read aloud, offers support when they stumble, and generates magical, personalized stories using generative AI. It works—and kids love it.

Now, we’re scaling that success into something even bigger: a complete AI teacher for all children. We’re building a real-time learning platform—one that combines language, speech, and memory to power personalized, interactive education for kids worldwide. We’re moving fast: we ship weekly, test directly with kids and families, and push the boundaries of what AI can do in education.

With the resources of the world's top investors and the heart of a public benefit corporation, we’re here to revolutionize how children learn globally. Featured on TIME’s Best Inventions and Fortune’s Change the World, Ello is a small, mission-driven team taking on one of the most important challenges of our time: to democratize education.
