What is HeartState Simulator?

Installed in 90 simulated worlds

HeartState Simulator is a free online HeartState simulator powered by AI. Open the HeartState Simulator in your browser and the app fills itself: an AI writes what is inside it, plays the other people, and reacts to whatever you do in the HeartState Simulator.

Unlike a static HeartState template or a screenshot generator, the HeartState Simulator keeps running. Every action you take in the HeartState Simulator gets an answer, and the world around the app moves on its own between your turns.

People use the HeartState Simulator to try things out safely, to roleplay, to make mockups and screenshots, to write stories, and to practise. The HeartState Simulator never connects to any real HeartState service: no login, no real account, nothing posted or sent anywhere.
