Questions
Is it safe to use while driving?
It's made to set and forget. Stories start on their own and need no taps while moving. Always follow local laws about phones in cars.
Can kids ask their own questions?
Yes, once a grown-up turns live AI on. Hold the button and ask “why is the bridge orange?”, or tap “What's here?” for a new story about where you are. Recordings aren't kept.
Does it need cell signal?
Hand-written stories are recorded ahead of time. Questions and new-area stories need signal.
