Good to know that you actually have kids yourself! That gives me some confidence that you are really trying to make this as safe and non-addictive as possible. Although it's not a product I would use (without supervision), I can see that you have good intentions.

Unless they have very specific questions, children encyclopedia books/apps already go a long way. I'm not sure it's really worth bringing in LLMs to achieve that last mile.

> For some reason, I don't see a lot of people criticizing that. Perhaps, because they don't market to kids. Kids just use it.

You are right. The broader issue is that so many parents allow their kids unsupervised access to the internet in the first place. I'm just wondering if these people really care enough to use your app instead...
