What is WorldOS?
WorldOS is a web site of AI worlds, at worldos.cc. It calls itself “your AI sandbox for any world.” Users make the worlds: war and history games, fandom worlds, romances, and life sims. You type what you do in plain words, and the AI plays out the story and the characters.
A world is built from small apps. Its site says you can chat with characters, watch social feeds react, trade in-world stocks, and browse a generated web. Creators can share their worlds, and they earn a share of the Zaps that paying players spend in them.
Each turn costs Zaps, its credits. You get free Zaps when you sign up, and again every 24 hours. Plans cost €5.99, €12.99, or €26.99 a month, and Zap packs start at €4.49. A Freedom Pass, at €8.99 a month, lets you use your own AI key. Its terms say you must be 18 or older. The terms name Entropia Inc. as the company.
What is LifeSim?
LifeSim is our game. It is a free life sim you play in the browser at play.lifesim.com, or in the iPhone app. You live one life in any real city on a 3D map of Earth. Every person in the city is an AI character with a job, a home, friends, a routine, and a memory of you. You talk to them in your own words.
We make LifeSim, so read this page with that in mind. We only state facts about WorldOS that its own pages state, and we link each one below.

Where WorldOS is stronger
Any genre. WorldOS has war games, history, sci-fi, fandoms, and romance, all made by users. LifeSim is one kind of game: a life in a real city.
Make and share worlds. On WorldOS you can build a world from apps, share it, and earn from it. LifeSim has no world editor and no creator payouts.
More screens in a world. A WorldOS world can have social feeds, in-world stocks, and a generated web. LifeSim has the real map and the people around you.
Where LifeSim is stronger
The real map. LifeSim puts you on a real 3D map of Earth, with real streets and places. You can search for a café and walk to it.
Nothing to count. LifeSim has no credits per turn, no ads, and nothing to buy. On WorldOS, each turn costs Zaps.
For teens too. LifeSim is rated 13+. WorldOS's terms say you must be 18.
Bring your character. You can import a character from Character.AI, Janitor AI, PolyBuzz, Emochi, and other apps, and it becomes a person in your new life.
Bring your WorldOS character with you
You don't have to start from zero. Copy the character's name, description, and personality, and take screenshots for the looks. In the LifeSim builder, open Import a character, pick Other app or game, and paste them. LifeSim writes the character as a person in your new life: a name, an age, a job, a past, a life goal, and who they are to you. It draws their looks in its own style.
Your chats and memories stay in WorldOS. Sexual content never comes over, because LifeSim is rated 13+. Read every app you can import a character from.
Your first week in LifeSim
You pick a city. Any city, on a real map of Earth. You give your character a name and a reason to be there. Then you step out onto a real street, and there are people on it.
They’re not waiting for you. They have jobs to get to, homes to go back to, friends they see on Fridays. Say hi to one of them, in your own words, and they answer in theirs. Tell them something and they keep it. Tell their friend something and it gets around.
By the end of the week you have a place you go in the mornings, someone you’re avoiding, and someone you’re not. One player once stayed for thirteen hours straight. We checked.
LifeSim is a free game, in the browser and on iPhone. No ads and nothing to buy. Season 1 is in beta.
What we could not check
We did not play every WorldOS world, and each one has its own rules and costs. We report what its pages say. Its terms name the company but not its country. Check worldos.cc for the latest prices.
Which one should you play?
Play WorldOS if you want to jump between many worlds, or build your own. Play LifeSim if you want one life in a real city, any city, where every person answers you and remembers you, for free.
