Group roleplay lets you put several AI characters in the same conversation, so they answer you and each other. On Junipero, group chats are part of Infinity+ and hold up to five characters. You start from any one-on-one chat, add a character, and the newcomer walks into the scene in character. This guide covers how it works, how to set up a cast that plays well together, and how to keep a busy scene coherent.

What an AI group chat is (and isn't)

In a one-on-one chat, every reply comes from the same character. In a group chat:

Several characters share one scene. Each keeps their own personality, description and voice.
Not everyone speaks every turn. After your message, Junipero picks who should respond, usually one to three characters, in an order that makes sense for the conversation.
Characters address each other. A skeptical detective can challenge the nervous witness, not just you.
You're still the lead. Your messages decide what the scene is about, and characters react to where you steer it.

It's different from a Scenario, where a single narrator describes the world and voices everyone in it. A Scenario is one AI playing a whole cast. A group chat is several distinct characters, each built separately, sharing a room. Both are useful: Scenarios are free and great for adventures, while group chats shine when you want specific characters you already know to meet.

How to start a group chat on Junipero

Open a chat with the first character. Any character works, including ones you created.
Add a participant. On mobile, open the chat's participants screen and tap Add participant. On the web, use the add participant option in the chat's side settings panel.
Pick a character. Search or browse community characters, or switch to your own private creations.
Watch them arrive. The new character gets an arrival turn: they enter the conversation and react to what's already going on.

When you add someone to a one-on-one chat, Junipero creates a new group chat with both characters in it. Your original one-on-one conversation is left untouched, so you can switch back to it anytime.

You can keep adding characters until there are five, remove anyone who isn't working, rename the group, and give each participant their own voice for read-aloud replies.

Building a cast that plays well together

A group scene is only as good as the chemistry between the characters. Some combinations that consistently work:

A clear conflict

Two characters who want opposite things give every turn energy. A treasure hunter who wants to open the tomb and a guardian who has sworn to keep it sealed will argue without any help from you.

Distinct voices

If two characters are both "calm, wise mentors", their replies will blur together. Aim for contrast in how they talk: one blunt and short, one dramatic and wordy, one who only asks questions.

A reason to be in the same place

Characters built for different worlds can still share a scene, but give them a reason. "You've all been summoned to the reading of the same will" is enough.

Roles, not just personalities

Think of the cast like a heist crew or an adventuring party: the planner, the muscle, the skeptic, the wildcard. Clear roles help the AI decide who should speak next.

If you're building characters specifically for group play, our guide on how to create an AI character in one sentence covers how to give each one a strong, specific want.

How to run a group roleplay well

Address characters by name

The simplest way to control who speaks is to talk to someone directly. "Mara, what did you see in the cellar?" makes it very likely Mara answers first.

Keep your turns focused

A message that asks three characters three different questions at once tends to scatter the replies. One clear action or question per turn keeps the scene readable.

Set up the scene early

Your first message in a new group sets the tone. Describe where everyone is and what's at stake: "The storm has trapped all of us in the lighthouse, and the keeper has just locked the only door."

Let them talk among themselves

Sometimes the strongest move is a short one: "I stay quiet and watch the two of them argue." That gives the characters room to interact.

Fix a turn that goes wrong

Regenerate a reply that misses the mark, or edit your own message and try again. Small corrections early keep the scene on track.

Keeping a group story consistent

Group chats use the same memory tools as one-on-one chats, applied to the whole conversation:

Automatic summaries condense older parts of the scene so the plot carries forward.
Long-term memories (Infinity and above) collect facts from the chat for you to confirm, edit or dismiss.
Fixed Memory (Infinity and above) holds a short note, like the scene's ground rules, that's included with every reply.
Lorebooks (Infinity and above) give the whole cast shared knowledge of your world's places, factions and history.

Since group chats are an Infinity+ feature, all of these are available whenever you're in one. For the full picture, see How AI Roleplay Memory Works.

Ideas for group scenes

The interrogation. A detective, a suspect and a lawyer. You're the one holding the evidence.
The council. Three rulers of rival kingdoms negotiate, and you're the only neutral voice.
The heist crew. A planner, a safecracker and a lookout, the night before the job.
The dinner party. Five guests, one secret, and the host hasn't come down yet.
The quest party. A knight, a thief and a scholar on the road, arguing over which way to go.

FAQ

How many AI characters can be in one group chat?

Up to five characters, plus you.

Is group chat free?

No. Group chats are part of the Infinity+ plan on both web and mobile. Scenarios, where one narrator voices a whole cast, are free. See pricing for plan details.

Do all characters reply to every message?

No. After each of your messages, Junipero chooses who should respond, usually one to three characters, based on who you addressed and what's happening in the scene.

Will adding a character change my existing chat?

No. Adding a character to a one-on-one chat creates a separate group chat. The original conversation stays exactly as it was.

Can I use characters I created in a group chat?

Yes. Your own characters, including private ones, can join a group alongside community characters.

Put your cast together

Pick two characters who would never agree on anything and put them in a room. Find characters in Explore or see what's included in Infinity+.
