What is Heartbeat Simulator?

Installed in 18 simulated worlds

Heartbeat Simulator is a free online Heartbeat simulator powered by AI. Open the Heartbeat 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 Heartbeat Simulator.

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

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