How to play a solo RPG with an AI Game Master.
You do not need a group, a human GM, or any rules memorized. An AI Game Master runs the world and plays every character, so you can sit down and play a role-playing game on your own in about a minute. Here is exactly how.
Free to play. Unlimited from $10/mo. Plays in your browser and on Android.
Playing an RPG used to mean getting a group together and finding someone willing to run the game. An AI Game Master removes both problems. It narrates the scene, voices the NPCs, tracks your character, and rolls the dice, the whole job a human GM does, so a solo session is just you and the AI. You play whenever you want, for as long as you want, and the story is waiting when you come back.
The one thing that separates a solo game you will actually stick with from one that falls apart is memory. If the AI forgets what happened a few sessions ago, your world stops making sense. So the steps below assume a Game Master that remembers, which is what Auferet is built around.
Why play this way
Why solo RPG with AI took off
The hardest part of a traditional RPG was never the rules, it was logistics: finding four or five people with a free evening, keeping a campaign alive when someone drops out, and relying on one person to prepare and run every session. Solo play with an AI removes all of that. There is no schedule to coordinate and no one to let down if you only have twenty minutes.
It also changes what you can play. You are not limited to what a group agrees on or what a GM has prepped. You can start a grim horror story at midnight, switch to a lighthearted heist the next day, and take a scene as slowly or as recklessly as you like, because the only person at the table is you. For a lot of players, that freedom, plus an AI that is available at any hour and never judges a strange idea, is the whole appeal.
The one thing that matters
The make-or-break factor: does it remember?
If you take one thing from this guide, take this: the quality of a solo AI RPG comes down to memory. Almost any modern AI can write a vivid opening scene. The problem shows up later. Ask a general chatbot to run a campaign and it will forget the name of the tavern by the third session, lose track of who you met, and contradict its own lore, because it only holds as much as fits in its context window.
This is the wall dedicated tools are built to solve, and it is what Auferet is designed around. Instead of hoping everything stays in context, it keeps your characters, places, and events in structured libraries that persist, and it can search the whole history of your adventure to pull the right detail back at the right moment. That is why a solo campaign holds together over dozens of sessions instead of quietly resetting. When you are choosing a tool, test this first: play past the point where a normal chatbot would forget, and see whether the world still knows what you did.
What it feels like
A solo session, start to finish
Here is what a first session actually feels like. You type a single line, say, "I am a smuggler hiding in a harbor town after a job went wrong." The Game Master opens on a rain-slick dock, describes the harbor master eyeing you, and asks what you do. You slip into a tavern; it names the place, introduces a nervous informant, and plays out the conversation in that character's voice. You lie to the informant, and the AI notes it.
A few sessions later you run into that same informant, and he remembers you lied. The town has the layout it had before, the job you botched is still hanging over the story, and a throwaway detail you invented in the first scene, a scar, a debt, a name, comes back as a plot thread. That continuity is the difference between a solo RPG and just chatting with an AI, and it is the whole reason to use a tool built for it.
One common question
Can't I just use a regular AI chatbot?
You can, and plenty of people start there: open a general AI chatbot, write a long prompt telling it to act as your Game Master, set the tone, and play. It is flexible and costs nothing. But it hits the same wall every time. You have to write and maintain that setup yourself, the AI drifts toward tired tropes unless you keep correcting it, and, worst of all, it forgets, so within a few sessions it has lost your NPCs, your choices, and your world's own rules.
A tool built for the job removes that friction. Auferet is the Game Master out of the box, with no system prompt to engineer, and it keeps your world in persistent memory instead of a shrinking context window, so continuity holds without you policing it. If you enjoy tinkering with prompts, the do-it-yourself route is a fun project. If you just want to sit down and play a solo campaign that remembers itself, a purpose-built tool is the shortcut.
Step by step
Five steps to your first solo session
Open the Game Master
Open Auferet in your browser, no download. The free tier includes every feature, 10 actions a day.
Describe your character and world
In plain words, say who you are and the story you want, any genre. Or turn on a system mode with a full sheet.
Let it open the scene
The AI narrates an opening and plays the NPCs. You just say what you do, in your own words.
Play and let the world respond
Explore, talk, fight. It resolves the dice, tracks your gear and stats, and reacts to your choices.
Come back anytime
No session to schedule. The campaign is saved with its memory, so you pick the same story back up whenever.
Getting more out of it
Tips for a solo campaign that lasts
Test the memory first
Play past the point where a lesser tool would forget, session ten and beyond, and see if the world still holds. That is the real test of a solo Game Master.
Bring your own world
If you already have a setting, upload it as a PDF or text file. The Game Master reads your canon and runs the adventure inside it.
Use rules only if you want them
Freeform is fine, just describe what you do. For structure, the 5e and Pathfinder 2e modes add sheets, checks, and a dice roller.
Let the world grow
Name places and people as you go. They are tracked and remembered, so a small opening scene can become a whole living region.
Talk to the NPCs
The Game Master plays them with their own motives. Real conversations, not menu choices, are where a solo story comes alive.
Invite a friend later
Solo is the default, but you can bring someone into the same world and take turns, then go back to solo whenever.
FAQ
Playing a solo RPG with AI, answered
Can you really play an RPG by yourself with AI?
Yes. The AI Game Master narrates the world, plays every NPC, tracks your character and inventory, and rolls the dice, so you can play a full RPG solo, at your own pace, with no group to gather.
What is the best free way to play a solo RPG with AI?
Look for a free tier that includes persistent memory, the part that makes a solo campaign hold together. Auferet is free to start with the full memory system and 10 actions a day; unlimited actions begin at $10/mo.
How do I keep a solo AI RPG consistent over a long story?
Use a Game Master built around memory. Auferet keeps your characters, places, and events in dedicated memory libraries that stay in context, so the world does not drift or forget your earlier choices.
Do I need to know any rules to play?
No. Play freeform by just describing what you do. If you prefer real rules, there are dedicated 5e and Pathfinder 2e modes with sheets and a dice roller.
Can I use my own setting or lore?
Yes. Upload a worldbook or notes as a PDF or text file, and the Game Master runs the adventure inside your own canon.
How is this different from just using a general AI chatbot?
A general chatbot can improvise a scene, but it forgets your story as it grows past its context window, so characters and past choices drift or reset. A tool built for RPGs keeps that world in persistent memory, which is what lets a solo campaign hold together over many sessions.
Can I play on my phone?
Yes. Auferet plays in any modern browser, so it works on a phone, tablet, or computer, and there's an Android app too. Your campaign and its memory are saved, so you can start on one device and continue on another.
What kinds of stories work best solo?
Almost any, but stories driven by your own choices shine solo: investigations, survival, exploration, heists, personal drama, or open sandbox worlds. With no group to coordinate, you can follow one thread as deep as you like and the AI keeps the consequences consistent.
