This is your main way to act, and the one box you'll use most. Type anything you want to do — "I sneak out the back door," "I propose a ceasefire," "I confront him about the lies" — and the world plays out what happens next. It fits roleplay, big decisions, investigating, negotiating, fleeing, attacking, making a public statement, almost anything. You don't need to write a lot: just say what you're doing and what you're hoping for. Stuck? Tap one of the AI's suggested moves to get going.

What is Main Input Simulator?

Installed in 54,537 simulated worlds

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

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

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