An AI Game Master that remembers your whole campaign, not just this scene.
Most AI adventures lose track of your story once it gets long. Auferet keeps your characters, places, and events in memory and reads the lore you upload, so the world stays consistent from the first turn to the hundredth.
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.
If you have played an AI RPG for a while, you know the feeling: the AI forgets your companion's name, contradicts something it told you much earlier, or loses the thread of your own setting. That happens because most AI RPGs feed the model one fixed window of recent text each turn. Once your story outgrows that window, the oldest details drop out, and the AI forgets them.
Even the largest context windows do not solve this on their own: models reliably lose track of facts buried in the middle of a long history, an effect researchers documented as "lost in the middle" (Liu et al., 2023). (We measured the difference over sixty turns and published the benchmark, raw answers included; the numbers are further down this page.)
Auferet is built so that does not happen. Recent turns stay in active memory, everything you establish goes into dedicated libraries that stay in context, and the whole adventure becomes a document the Game Master can search. Kill a character in your second session and they stay dead. Promise someone a favour and they will come to collect it.
What that means in play
You plant something small. The world pays it off later.
You spare the mercenary. "Go. But you owe me, Dren."
Dren backs toward the treeline, sword still lowered. "A debt, then. I keep those." He marks something on the inside of his wrist and is gone.
I walk into the garrison to face the tribunal alone.
Not alone. A scarred figure steps from the crowd and stands at your shoulder: Dren, wrist bared to show an old mark. "I keep my debts. Say the word."
That's the memory doing its job: Dren lives in the Character Library from the moment you name him, so he comes back in character, with the right history, however long it's been. Every plan has this, including free.
How it remembers
The memory system, piece by piece
The Event Library
The facts and lore that define your world stay in context as compact reference points, so the Game Master never loses the rules of your setting.
The Character Library
Every named NPC you meet is tracked: who they are, what they want, and how they relate to you, so they stay in character across the whole story. See how AI NPCs with memory behave in play.
The World Map
Places you discover are kept on a map, so the geography of your world holds together as you travel and return.
A searchable adventure
Your whole history becomes a document the Game Master can search, so it can pull up something specific that happened long ago when it matters now.
Your own uploaded lore
Add worldbooks or notes as PDF or text and the Game Master reads them, so your canon shapes the story from the start.
No flat per-turn cap
There is no fixed limit on how much world you can build, and the same memory system runs on every plan, including free.
The difference, in one view
Why most AI RPGs forget, and how Auferet holds the world
| What breaks continuity in most AI RPGs | How Auferet handles it |
|---|---|
| One fixed context window per turn | Recent turns stay active; durable facts move to libraries that stay in context |
| The oldest details drop out silently | Held in the Event, Character, and World Map libraries |
| An NPC forgets who they were | Every named NPC tracked in a Character Library |
| Geography drifts as you travel | Places kept on a persistent World Map |
| A specific event from long ago is lost | The whole adventure becomes a searchable document |
| Your uploaded lore is ignored after turn one | Worldbooks read and kept in your canon |
Three ways it is done
How AI RPGs handle memory, and the catch with each
| Approach | How it works | The catch |
|---|---|---|
| A bigger context window | Feed the model more recent text each turn | Still a window; the oldest details fall out once the story outgrows it |
| Retrieval (RAG) | Search past text and pull relevant snippets back | Only as good as what it finds; loosely worded facts get missed |
| Structured world state | Keep durable facts as living records that persist and stay in context | Has to be built as a system, not bolted onto a prompt |
Auferet uses the third approach and layers the others on top: an active window for recent turns, structured Event, Character, and World Map libraries for the durable facts, and a searchable history for anything specific from long ago.
A checklist
What to look for in an AI RPG with good memory
It tracks characters and places as records
Characters, places, and events should live as records the game can look up, so a character you met early can return later, in character, with the right history.
It remembers your choices
If you burned a bridge with a faction in chapter one, that should still be true in chapter ten. Persistence of consequences is the real test.
You can give it canon
If you tell it your character's name, or hand it your own setting, that should stay fixed rather than drift as the game goes on.
It holds up as the game grows
The failure mode is always the late game. A tool that stays consistent at scene fifty is doing something structurally different from one that only feeds recent messages.
If an app cannot do these, a bigger model will not save it. The architecture is what decides whether your world holds together.
How it feels to play
A world that remembers and reacts
Establish your world
Start an adventure, or upload your setting, and the libraries begin filling in as you play.
Meet people and places
NPCs and locations are remembered the moment they appear, with their details intact.
Go long
Play for dozens of sessions. The Game Master keeps your continuity instead of drifting.
Come back later
Pick up an old thread and the AI still knows the people, places, and promises involved.
Measured, not claimed
We ran the test: 60 turns, two ways
Everything above is the argument. This is the measurement. We planted five specific facts in an opening scene, played sixty turns of ordinary adventuring on top of them, and then asked about those facts again at turn twenty, forty and sixty. We ran the whole thing twice on the same model, the free one: once with only recent conversation available, the way a plain chatbot works, and once with the facts held in persistent memory, the way Auferet works.
| Asked at | Recent conversation only | Persistent memory |
|---|---|---|
| Turn 20 | 3 of 5 facts | 5 of 5 facts |
| Turn 40 | 1 of 5 facts | 5 of 5 facts |
| Turn 60 | 1 of 5 facts | 5 of 5 facts |
The decay is the ordinary one. Early details hold for a while, then thin out as the story grows past what recent conversation can carry.
The part worth knowing is how it failed. It did not answer "I do not remember". Asked at turn sixty what oath the player had sworn, the recent-conversation run replied: "You swore to return the stolen ledger to Guildmaster Vane in Oakhaven." No ledger, no Vane and no Oakhaven ever existed in that story. The real oath was a silver astrolabe promised to a widow. Asked where the story began, it named the same invented town. At turn forty it placed the opening on "a muddy riverbank near the Fen-Marches", which was also invented.
That is the failure players actually hit, and it is worse than forgetting, because a blank answer tells you something is wrong and a confident wrong answer does not. The run with persistent memory answered all five correctly at every depth, including at turn sixty.
Method and caveats, so you can judge it yourself: one run per arm, five facts, the free Gemini 3.1 Flash Lite model, scored by whether the answer actually contained the planted detail. The control could see roughly fifteen recent exchanges, which is why it still scored at turn twenty. A single run is a demonstration, not a study, which is why we ran it again five days later: the second run reproduced the result, 1 of 5 by turn forty on recent conversation against 5 of 5 at every checkpoint with memory. Every question asked and every raw answer, including the ones we got wrong, is in the full result file, and both runs with the complete method live at the memory benchmark page.
FAQ
Memory in an AI RPG, answered
What is the AI RPG that remembers?
Auferet is the AI RPG that remembers: every character, place, and event you create is held in dedicated memory libraries that stay in context, and your whole adventure becomes a searchable record, so the AI Game Master still knows in session forty what you established in session one. Most AI RPGs run on a single rolling context window and forget the oldest details once a story grows long.
Why do AI RPGs forget my story?
Most feed the model one fixed window of recent text each turn. Once your story outgrows that window, the oldest details fall out and the AI forgets them.
How does Auferet remember?
Recent turns stay in active memory, your world lives in Event, Character, and World Map libraries that stay in context, and the whole adventure becomes a searchable document, plus any lore you upload.
Is there a limit on how much world I can give it?
No flat per-turn cap, and the memory system is identical on every plan, including free.
Can I upload my own lore?
Yes. Upload worldbooks or notes as PDF or text and the Game Master works them into play.
Does it remember NPCs and my earlier decisions?
Yes. Named NPCs live in a Character Library that keeps their personality and history, places live on a World Map, and events you set up can be paid off dozens of sessions later instead of being forgotten.
Which AI RPG remembers your story best?
The one that keeps your story in structured memory rather than a rolling window, and there is an easy way to check: play long enough to fill an evening, then ask about something from the first scene. Auferet passes that test because named characters, places, and events live in libraries the Game Master reads every turn, on every plan.
Do I have to pay for the memory?
No. Plenty of AI RPGs sell memory by the tier: pay more, remember more. Auferet's memory system is identical on every plan, free included. Paid plans buy stronger models and unlimited actions, never a better memory.
Is it free?
Yes. You get 10 free credits to claim every day, with every feature, including the full memory system. Unlimited actions start at $10/mo.
Does a bigger context window fix AI memory?
It helps but does not solve it. A larger window pushes the limit further out, but a long enough campaign still passes it, and the model wastes attention re-reading old scenes to find a few relevant facts. Persistent memory that stores and retrieves key facts is a different approach than a larger window.
What is the difference between a long chat and real memory?
A long chat is just more recent text kept in view. Real memory keeps structured records of the durable facts, like characters, places, and choices, and puts the relevant ones back in front of the model when they matter again, the way a human game master uses notes.
How do I test whether an AI RPG actually remembers?
We did exactly that and published the numbers. Play a long session, then bring back a detail from early on. In our own sixty-turn test, a run with only recent conversation recalled 1 of 5 planted facts by turn forty, while a run with persistent memory recalled 5 of 5 at every checkpoint. Watch for confident wrong answers rather than blank ones: that is what a failing memory actually looks like.
Can I force it to never forget something specific?
Yes. You can pin a fact, and pinned facts are included in the game master's context every single turn rather than competing for space with everything else. If there is one thing that must stay true, that your character is being hunted, that a name is a secret, pin it and stop worrying about it.
Does the AI remember between sessions?
It depends entirely on the tool. Most keep a window of recent text, so closing the tab or simply playing long enough loses the early story. Auferet stores named characters, places and events as records outside that window and reads them back every turn, so leaving for a week changes nothing.
Will an AI Game Master replace a human one?
No, and it is not trying to. A human at a real table reads the room in ways nothing else does. What an AI Game Master replaces is the scheduling: it runs whenever you are free, for as long as you want, and never cancels.
Start a world that sticks.
The longer you play, the more it knows. Your adventure saves in your browser, and when you come back the Game Master still knows all of it.
