ANIM is a free service centered on meeting and nurturing a one-of-a-kind companion called an Anim. Each Anim begins as an egg, and users can stay alongside it as it awakens and begin sharing daily life. The experience focuses on gradual companionship: users can talk to their Anim in a room, and it responds and becomes more familiar over time. As they spend time together from hatching onward, the Anim’s appearance and words gradually develop, making each relationship and character distinct.

ANIM also offers ways to broaden this small world. Through interactions, users can encounter other Anims, while their owners can get to know one another and connect in a relaxed way. Soft background music is available to help users feel immersed in the setting, with the option to continue without sound. The service provides account login, frequently asked questions, updates through ANIM’s newsletter, and information about its operator, terms of use, and privacy policy.
