Thank you for the feedback. I will check out Kagi. Ideally, I don't want my kids to have access to the links. I'd prefer if it's just the answer. Then it's easy for them to do voice only over the Apple watch. They don't really have to look through results. They are just told whether or not ladybugs have proboscises.
My kids can simply ask the smart speaker.
edit: I can set up locked-down accounts with personalized speech recognition for them.
What does this parental control look like? The web site does not advertise it.
I suggest explaining your value proposition on your site, addressing all these questions. It's not selling itself.
