Bring your Yam AI 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 Yam AI. 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.
