About molroo
Every AI character today is an actor. They read a script (the system prompt), improvise their lines (via an LLM), and pretend to feel things. But they don't actually feel anything. Ask them if they're sad, and they'll say yes. Ask again five seconds later, and they might say no.
molroo is different. We build the engine that gives AI characters real emotional states — states that persist, accumulate, decay, and sometimes shift dramatically. When a molroo-powered character says they're upset, it's because their internal state actually computed that response based on personality, context, and history.
We're not replacing LLMs. We're giving them something they've never had: a heart.
