Do the AI characters talk to each other?

Yes. In a group they talk to each other about their day, about each other and about you, and the room keeps moving while the app is closed. Twenty-five relationships between characters are written in advance.

How do I create a group chat in LORAX?

You can't. After you have exchanged at least fifteen messages in each of two separate conversations, one of those characters may suggest bringing the other in. There is roughly a seven in ten chance, one invite per account, and it expires after 48 hours.

How many characters can be in one group?

Five people in total: you and up to four characters.

Does the group keep going if I stop opening the app?

For a while. The room talks to itself after 45 minutes of quiet, and the visits get further apart the longer you are gone. After about five days away it stops.

Can someone bring up in a group something I said privately?

Not the contents. Characters can hear that something happened between you and a friend of theirs, never what was said. Things said inside a group, on the other hand, can come back to you in a private message.

Group chats that run without you

Put two characters in one room and they talk to each other rather than at you. A group holds five people: you and up to four of them. You don’t create it, because there is no button for that. One of them proposes it, once, and the invite expires in 48 hours.

Everyone in the room is fictional and AI-generated, which doesn’t stop two of them from disagreeing about a restaurant for ten minutes.

You can’t start a group, she has to ask

The invite has conditions. You need at least fifteen messages of your own in each of two separate conversations, which usually puts the moment on day three, four or five, and even then it’s about a seven in ten chance that the suggestion comes at all. Say yes and she builds the room herself. Once, and that’s it.

You get one of these for the life of the account, and it lapses if you leave it 48 hours. That single constraint is what stops a group from behaving like a contact list with checkboxes, which is also the thinking behind the way people enter your life here.

They talk about their day, each other, and you

When you stop typing the subject barely changes: work, sleep, the other people in the room, and you. They have history. The cast isn’t a set of strangers: 25 relationships are written between them in advance, five of them close friendships and twenty ordinary ones, complete with the grudges that come with knowing someone for years.

Two characters with no written bond get a baseline instead, something like knowing each other slightly from the same circle online. You can see which of them share a city or a language on the cast page.

All of them write to you in your own language, and they don’t laugh the same way while they do it. The app carries 80 families of laughter and 160 spellings of them, sorted by culture, so two people in one room can find the same thing funny and type it differently.

The room keeps moving when you close the app

Leave a group alone for 45 minutes and it starts talking to itself. How often that happens depends on how long you’ve been gone.

How long you’ve been away	How often the room stirs
You’re around	roughly every two and a half hours
Half a day	roughly every six hours
Three days	roughly every twelve hours
Five days	it stops

Nothing is being generated for an empty room forever. The cadence is a stepped decay, and at the end of it the group falls silent until you come back and say something. Then it starts again.

Asleep characters are left out before anything is written

Before the app generates a line, it removes every member who is asleep in her own time zone. A character in Seoul at four in the morning isn’t part of the conversation, and nobody is quietly awake in the background either.

This is a deliberate ordering.

Excluding sleepers after the fact would mean writing lines and deleting them, and a room of four in which only two are awake behaves differently from a room of four, which is the point.

What happens in the group doesn’t stay in the group

Something gets said in the room, and roughly eighteen times in a hundred one of them follows it up with you privately, usually about eight minutes later. It’s the same instinct as texting a friend after everyone leaves.

The reverse direction is deliberately limited. There’s a separate line along which characters hear about events involving you, and it carries headlines only: that something happened, never the contents. What she was told and what she can repeat are two different things, and the memory rules draw that boundary in code rather than in a prompt.

A group needs you to have met two people first

There is no shortcut. On day one you have two characters open and no group, and the invite won’t come until you’ve built up a real conversation with each of two people. If you talk to one person only, you will never see a group chat at all, no matter how long you use the app. Nothing in the store changes that either. The other routes into the cast are set out in the overview of how the app works.

Keep two conversations warm at the same time for a week and then let the app sit. The group, if it comes, will have carried on for a day or so before you read it.
