Congratulations on the launching to real users. I know how challenging that is and especially when your users are kids, I can imagine the pressure is much higher.
One piece of feedback on your use of the term AI. While adding the term "AI" to the description of /most/ products seems to increase their appeal, in products that are for children, to me, it reads like this product will be buggy at best and ends up decreasing the appeal. Words like researched, "smart", advanced, cutting-edge etc may be better suited. This is just one person's reaction, of course. I could be wrong--perhaps to non-engineers, reading "AI" on kids' products now has a more positive reaction.
