I'm curious whether you're using this to teach initial familiarity, or as the first step toward touch typing?
For touch typing, I think Typing Club is a good place to start for kids. And then Keybr to develop full fluency. And then Monkeytype to develop speed.
EDIT - when I wrote this comment I had only opened the link on my phone. Now I see it on desktop it's clear that the on-screen keyboard is intended to teach key positions without the user looking down at their keyboard. It's good.
In case anyone else was curious, `ai.studio/apps` apps apparently require a google account login by default. Google ai-mode says allowing public access is an author option, but then (1) API costs are borne by the author, and (2) there are some (unclear) compliance implications.
