A voice-interactive AI pet running on a Raspberry Pi, built with Meta's Model API. Speech recognition and speech output run locally on the Pi; the child talks to the pet with no screen and no keyboard. The API key is held and managed by a parent, with a monthly spend limit and the cost of every interaction printed — so a child under 13 can build an AI project safely and legally. What makes it different from a plain chatbot: (1) A pet that remembers — long-term memory stored locally on the Pi: the pet remembers the child's name, what they like, and what they said yesterday, and asks about it. (2) Screen-free by design — voice only, microphone and speaker are the whole interface. (3) Parent holds the key — the key, the spend cap and the per-interaction cost are the parent's. (4) Bilingual, and it teaches back — the pet switches between Chinese and English, asks the child questions, practices English with them, and learns new tricks the child teaches it, and remembers them.
