What features would parents value in an AI storytelling/companion app for kids?

I’m working on a project where kids can talk with AI companions (dragons, wizards, princesses, goblins) whose voices are generated with ElevenLabs. Parents have a control panel where they can manage the characters and upload knowledge. The system can also generate audiobooks, coloring pages, and themed songs, all tied to the stories.

Some ideas I’m considering:

Calm Castle: a calming, Headspace-like mode for kids

Games Portal: but I’m unsure what kinds of games would make sense

I’d love to hear from parents (or others with ideas) about what features would be most valuable.
