AI companion
An AI companion is a chatbot designed for ongoing personal conversation, friendship or role-play rather than for getting tasks done.
Also called AI friend, companion chatbot, AI girlfriend, AI boyfriend
In more detail
Companion apps give the AI a persistent personality and memory of past chats, so it feels like talking to the same character over time.
They can be comforting or fun, but experts warn about emotional dependence, especially for young or lonely users, and about how intimate conversations are stored. See anthropomorphism and AI privacy.
