How AI Companions Actually Work

Behind every reply is a system built from layers: personality, memory, mood. In this guide we open the hood, without giving away trade secrets, to explain what makes a conversation feel alive.

Personality first

Every companion starts from a written identity — her character, her voice, her limits — and adapts to you over time within those boundaries.

Memory that lasts

What you share does not vanish at the end of a session: names, running jokes, things you told her weeks ago can resurface, exactly like with someone who actually remembers you.
