Calls Simulator

Voice and video calls with your characters — in their own voice, live.

by WorldOS · 1166 worlds use this

Install

Call any character: a voice call in their own cloned voice, or a live video call if they have a portrait. Characters can call you too when the story calls for it (or when you ask them to) — answer with voice or video, or decline. Calls are billed per second while connected, and what was said on the call stays in the story.

What is Calls Simulator?

Installed in 1,166 simulated worlds

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

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

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

Why use Calls Simulator?

Free Calls Simulator online: no download, no signup to try.
The Calls Simulator runs on AI. Content, people and reactions are generated, not typed in by hand.
Safe: the Calls Simulator never touches the real Calls. No login, no real account, nothing published.
Screenshot-ready: the Calls Simulator looks like the real thing and carries no watermark.
