What is an AI companion?
An AI companion is a virtual character powered by artificial intelligence that can hold a conversation, respond to emotional cues and evolve with your interactions. Unlike a productivity assistant, a companion is not there to book meetings. It is there to talk, listen, joke and keep you company. An AI girlfriend is one type of AI companion; others include AI boyfriends, friends and story characters.

How to use an AI companion in a healthy way
- Treat it as one part of your social life, not all of it.
- Set a rough time budget if you notice you chat for hours every day.
- Remember that the companion is fictional and its replies are generated by AI.
- If you are going through a crisis, contact people you trust or a local helpline or professional. An AI cannot help in an emergency.
