SHORT ANSWER
An AI pet is an artificial companion designed around creature-like continuity, interaction, and care. It may be physical or virtual and may use rules, machine learning, or generative models. What distinguishes it from a generic assistant is an ongoing embodied or simulated identity.
The defining features
Useful criteria include a persistent identity, expressive behavior, responsiveness, some degree of autonomy, and a relationship loop that develops across encounters. Not every product needs every feature.
Physical AI pets
Robot dogs, soft companions, and smart plush toys can use movement, touch, sound, and proximity. Their body creates presence but also introduces cost, maintenance, and safety constraints.
Virtual AI pets
Apps, games, browser worlds, and mixed-reality creatures can support richer environments and faster updates. Their presence depends on a screen or headset, but their state can travel across devices.
AI is not one technology
A product may combine scripted animation, behavior rules, classifiers, speech recognition, and a language model. Calling the entire pet “an AI” can obscure which component actually does what.
