I did. A poorly behaved student would close the page. How are you going to stop that? Real children don't pay attention in the classroom.

Personally I found the demo kind of cringe - why the drake meme? Computers do not "struggle with too many digits" why use a metaphor that's just wrong?

With the "1 to 2 Machine" Demo the only feedback you get on no action is "green box is looking a bit empty." Not engaging really.

I think this would be useful for a motivated kid, but in that case Khan Academy already has way more content and is free. Don't see why you'd pay $50/month. That's to say nothing of YouTube which has even more content than Khan Academy, and is again free (or $15 if you don't want the ads).

Finally, I don't really see the "AI" here. The demo as constructed is basically a Google Slide deck with some JavaScript sprinkled in. A true "AI" experience would be that you, at any moment can ask for help and contextually it would help you. So in the case I described earlier it might go back and redisplay with arrows, or perhaps make the colors even more obvious.
