Isn't this moving the goalposts? It's great that you're learning but MathAcademy appears to be a whole product that may incorporate an LLM but is much more, and it's a paid product none of us can evaluate. It's not possible to tell from looking at their site, or from your comment, what content is generated, or how it is verified before being used as teaching material.

There are probably smart ways to incorporate LLM output into an application like the one you're lauding but your comment is a little like responding "but my cake tastes good" to someone who says you shouldn't eat raw flour.
