A multiplayer AI RPG you play with friends.
Invite your friends into the same adventure and take turns together in real time, with one AI Game Master running the shared world for the whole party.
Or jump straight in, no setup:
Free to play in your browser and on Android. The full memory system is on every plan, including free.
Auferet is a multiplayer AI RPG. You invite friends into one shared world, and a single Game Master runs it for everyone, except the Game Master is the AI, not the one friend who always gets stuck running it. Everyone rolls a character. Everyone plays. The party shares the same scene, the same NPCs, and the same memory, so what one player does is part of the story the rest are in.
It is the feel of a tabletop night without the prep. Auferet describes the world, voices the NPCs, tracks the party, and resolves what happens, so nobody has to read a rulebook to run the table. You take turns in real time, and the AI folds each action into the same scene instead of splitting the group into separate chats. When you want a quieter session, the same world plays solo.
See it run
A session with two players, recorded
This is not a description of how it would go. On 2026-09-10, two browsers on two fresh accounts, free-tier model. Mara started a world from one line, "I'm a caravan guard arriving at a mountain inn on the night a merchant caravan fails to return", and hosted a game in shared-world mode. Teodor joined with the six-character invite code. Each of them played in their own thread, and then Mara asked her Game Master about him:
The wind howls through the narrow pass, biting through your leather tunic as you crest the final ridge. Ahead, the solitary lantern of the Black Crag Inn flickers, but the usual warmth of the hearth seems absent. As you approach the heavy oak door, it slams shut with a jarring thud, followed by the frantic scraping of a heavy iron bolt sliding into place from within. A muffled, terrified voice cries out from behind the wood, "It's not safe! Keep away, whatever you are!" What do you do?
MaraI push through the inn's door and ask the room who last saw the caravan.
Game Master, to MaraYou put your shoulder into the wood, and with a sharp crack of splintering iron, the bolt gives way. You stumble into the dim, drafty common room, where a thin man with grey hair stands behind the bar, clutching a heavy iron poker. He gasps, eyes wide in the light of your lantern, and drops the weapon. "The caravan?" he stammers, pointing a shaky finger toward the dark, empty tables. "The last man to see them was a trader named Silas, but he hasn't been back for three days, and the road has been silent ever since."
Teodor, in his own browserI check the stables behind the inn for the caravan's horses and anything left on them.
Game Master, to TeodorYou step out into the biting wind and make your way toward the stables behind the inn. The structure is drafty and smells of damp straw and horse musk. Inside, you find a few of the caravan's horses, their heads low, shivering in their stalls. Tucked away in the corner of one stall, abandoned in the straw, sits a worn leather satchel.
MaraWhere is Teodor right now, and what has he found?
Game Master, to MaraTeodor is currently at the Black Crag Inn stables [1.1], just behind the main building where you are. As of his last action, he was searching that area for the caravan's horses and any remaining cargo, though his findings have not yet been reported to you.
Mara's Game Master never narrated Teodor's turn. It knew where he was and what he was doing because the session keeps one shared record of every player's location and last action, and each player's Game Master reads that record before it writes. Nobody's turn waited on anybody else's.
Player lists as each browser showed them: Mara (you) and Teodor in Mara's browser, Mara and Teodor (you) in Teodor's. A guest starts their own thread inside the host's world: pick one of the world's characters, or describe your own and the Game Master opens it for you. The whole session, both threads and both lists, is published as a JSON file.

FAQ
Multiplayer AI RPG, answered
Can I play an AI RPG with friends?
Yes. Invite friends into the same adventure and take turns together in real time, with one AI Game Master for the whole group.
How does multiplayer work?
Your group shares one world and one Game Master. You take turns acting, and the AI responds to the whole party.
Does everyone need to be online together?
You take turns in real time when the group is online. You can also play the same world solo whenever you want.
Is it free?
You get 10 free credits to claim every day, with every feature. Unlimited actions start at $10/mo.
Can we use real system rules?
Yes. There are 5e and Pathfinder 2e modes with stat tracking and a dice roller.
How do friends join the same game?
Start solo and invite friends with a share code to join the same adventure and take turns in real time. The shared world stays consistent for everyone, because the Game Master keeps one memory of the characters, places, and events across the group.
Do we have to wait for each other's turns?
Only if you choose to. There are four ways to run a group: host only, where one person drives and everyone else watches and advises; turn based, where you act in order; free for all, where anyone can act whenever they want; and shared world, where each player has their own thread running at their own pace. Pick the one that suits the group and change it later if it is not working.
Can we play at different times instead of all being online together?
Yes, in shared world mode. Each player gets their own game master thread and plays whenever they are free, while a shared world event log keeps every thread aware of what the others have been doing. Nobody sits waiting for a friend to come online, and the world still moves as one place rather than splitting into unrelated stories.
Can the party split up and regroup?
Yes. Two players can merge into the same scene to play a stretch together, then split apart again and go their own way. That is the part most group play gets wrong: you either move as one blob forever, or you fracture into separate games that stop mattering to each other.
Does the game master know what my friend did in their own scene?
Yes. Actions land in a shared world event log, so what your friend broke, bought or angered is known to the world and can come back on you later. That is what makes it one campaign rather than several people playing near each other.
Can we each play a completely different character?
Yes. Everyone brings their own character with their own traits and their own sheet, and the game master keeps each of you distinct rather than blurring the party into one voice. You can play freeform, or run real 5e or Pathfinder 2e characters with stats and dice.
Do all of us need to pay to play together?
No. The free tier includes every feature and claims 10 credits a day, so a friend can join your world without buying anything. Unlimited actions start at $10 a month if someone plays enough to want them.
Is there a multiplayer AI RPG that works for just two people?
This does, and two is the most common size. Start solo, send one share code, and you have a two player game with a game master running the world for both of you. Nothing here needs a full table to work.
Can AI characters be in the party too?
Yes. The game master plays every character you meet, and that includes companions who travel with you: a hireling, a rival, a loyal friend your character picked up along the way. The AI runs them scene to scene, remembers them, and keeps them consistent, so a party of one human is never actually alone. Human friends join with a share code; AI companions are already in the world.
