What is multiplayer AI?

Multiplayer AI is an AI agent that several people use together in one live session, instead of each person having a private chat with it. There is one conversation, one memory and one set of files for the group; anyone in the room can add context by posting it, redirect the agent with the next message, or pick up a task where the last person left it. The opposite is what most AI tools are: single-player, one person alone at a keyboard, with a history nobody else can see. This page defines the term, then shows what it means mechanically in Ergod, which is built this way: the room is the unit and a person is a member of it.

One · The definition

Four things have to be true, or it is not multiplayer.

A group chat where everyone pastes the same bot’s answers is not multiplayer AI; each person still has a private session and the group is copying between them. The word earns its meaning when the session itself is shared:

One historyThe agent sees everyone’s messages in order, so a question from one person is answered with what another person said a minute ago already in view. In Ergod a channel’s shared room and a web room are exactly this: one conversation the members read and write.
One memory and one workspaceFacts the group establishes and files the agent makes belong to the room, not to whoever happened to ask. Personal memory stays personal: in a shared session Ergod saves only collaborative facts to the room’s memory, and your own preferences stay in your own.
Anyone can steerAdding context is posting it. Redirecting is sending the next message. There is no owner whose turn it has to be; the person who asked can stop a turn mid-way, and the next message from anyone continues from the shared history.
Hand-off is freeLeaving a task in the room is handing it off. The next person reads what happened instead of being told, and the files are already where they need to be. Nobody re-explains the project.
Two · In practice

How Ergod does it, and who pays for what.

Ergod has four kinds of shared session, and one accounting rule for all of them: the host provides storage, every message is metered to whoever sent it, and joining is never gated by plan.

A Discord channel’s roomAny channel can have one. The first time you speak there with no saved choice, your request is held and Ergod asks: Shared room or Just me. Whoever hosts carries the room’s storage; a Free account hosts one at a time, Pro more. Replies and files post in the channel either way, so everyone there sees the work.
A voice channel or a DM, with a table in itThe Discord Activity puts a room in a voice channel: propose, vote, watch the winner get built, play it. Opened from a DM or a group DM, it gives that DM one table of its own. Nobody has to be an admin.
A web roomOpened from the dashboard’s Rooms tab; an invite code admits one person and expires in a day, and a member on any plan can be in it. Its chat, files and game tables are shared with whoever joins.
Catching up afterwardsNot everyone was on the call. From the browser, Catch up shows a room’s recent turns and files without entering, and Continue together picks the shared conversation back up. A Discord room opens read-only there, with Open in Discord to take part.
Telegram groupsAdd the bot to a group and it answers when addressed by name or by reply, with usage charged to whoever spoke. The same fourteen games open inside Telegram once the bot is set up for it.

The walkthrough of each one — every button, who hosts, what a watcher sees — is on Shared sessions, three ways.

What an AI player adds to a multiplayer experience.

The other half of the phrase is games. A bot improves a multiplayer night when it fills the seat nobody has, hosts the round nobody wants to referee, and gets better against the people it plays. In Ergod that is concrete:

It takes a seatIn Checkers, Chess, Four in a Row, Reversi, Mancala, Nine Men’s Morris, Backgammon, Dominoes and Crazy Eights, Ergod plays the other side. The rules live on the server: it can only choose among the legal moves the server lists, so it never invents one, and every move a person makes is checked the same way.
It hosts the roomIn Bingo, Live Quiz, Categories and Spymasters it calls, judges and keeps score without holding a seat, and fills empty seats so one person can start a real field. A Tournament sheet runs a bracket for whatever the room is playing.
It learns between matchesBefore each move it is handed what happened the last times this exact position came up and its own notes from earlier games at this table, so a line that beat it once is a line it has seen.
It talks, if you let itA Voice switch, off until you turn it on, says its table lines aloud in the voice you pick; a Music switch, on by default, plays a quiet loop keyed to the game. Both are yours alone, and its spoken line is metered to the same person as the move.
House rules are the room’sEvery game has settings the host sets from the table, baked in at the start so a mid-game change cannot rewrite a running match. All fourteen games, one page each.

What is multiplayer AI?

Multiplayer AI is an AI agent several people use together in one live session: one conversation, one memory and one set of files for the group, where anyone can add context by posting it, redirect the agent with the next message, and pick up a task where the last person left it. Most AI tools are single-player, one person alone with a private history. Ergod is built the multiplayer way: a Discord channel’s shared room, a voice-channel or DM Activity, a web room by invite code, and a Telegram group are all one agent shared by the people in them.

How do you improve a multiplayer experience with AI bots?

Give the bot the room, not the person, and give it a job the room lacks. In Ergod the agent lives where the group already talks, so ideas and builds happen in front of everyone; at the table it takes the empty seat in nine board and card games, choosing only among the legal moves the server lists, hosts Bingo, Live Quiz, Categories and Spymasters, fills seats so one person can start, is handed its own notes from earlier matches before each move, and can say its lines aloud. House rules are set from the table and each person spends their own usage.

Who pays when several people share one AI agent?

The person who sends each message spends their own usage, on any plan, and joining a room is never gated by plan. The host’s account carries the room’s storage, which is what “Free hosts one room at a time” limits. Nobody pays for the room itself and nobody is locked out of it for being on the free tier.

Try it with your people.

Free tier, no card, nothing to install. Open a web room from the dashboard, or add Ergod to a server and start a room in any channel. The argument for the category is on the multiplayer AI agent page.
