What is Lifespan Simulator?

Installed in 62 simulated worlds

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

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

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