Flexi: building an AI tutor at scale

Can AI actually help children learn better – or are schools still too slow, too scared, and too locked into the old system?

Neeru Khosla, co-founder of CK-12 Foundation, believes this moment could become a turning point for education. After nearly two decades building free learning tools for students and teachers, she argues that AI is our chance to finally understand how students think, where they get stuck, and how to help each child learn in a way that works for them.

*In this episode of Inference, we get into:*

- Why prompting is not cheating, but a real learning skill

- Why textbooks alone were never enough for deep understanding

- What C means in CK-12 (it’s important!)

- What Neeru learned from launching Flexi, CK-12’s AI tutor, now used by millions of students

- Why standardized testing misses the most important part of learning

- Why teachers need support, visibility, and confidence – not fear

- Why AI literacy may become as fundamental as reading, writing, and math

- How curiosity, mentorship, and community shape better learning outcomes

- Why “attention is all you need” is no longer enough – and what we need now

We also talk about public school inertia, philanthropy, core values when raising kids, and why Neeru believes AI should be used as augmented intelligence – not something to fear, but something to help humans grow.

This is a conversation about education, equity, curiosity, and what it would really take to build a learning system that works for every child. Watch it. I’m really passionate about this topic and think that everyone should think and talk more about it.
