Run a 5e campaign with an AI Game Master.
Auferet runs a real fifth edition game. It describes the scene, plays every NPC, calls for checks and saves, runs combat in initiative order, and keeps your character sheet up to date. Free to start, solo or with friends.
Or jump straight in, no setup:
Pick 5e mode in setup for the full sheet, checks and initiative. Memory is on every plan, including free.
Auferet is an AI Game Master built for fifth edition. Turn on 5e mode and the AI runs the table the way a table runs. It sets the difficulty class, asks you to roll a d20 and add the right modifier, and grants advantage or disadvantage when the situation earns it. It knows a Persuasion check from a Wisdom save, adds your proficiency bonus as you level, and leans on fifth edition's bounded accuracy, so a first-level rogue and a tenth-level fighter still play the same game.
No group, no scheduled night. Describe a character and the AI opens a scene, plays the NPCs, and keeps your whole fifth edition sheet current while you play. It runs both the 2014 rules and the 2024 update, so bring whichever your table uses.
See it run
A 5e turn, the way the AI plays it
A goblin lunges at you out of the dark. The AI rolls initiative for both sides and drops you into turn order. On your turn you get your movement, an action, and a bonus action, and the AI holds you to that. You call a sneak attack. It asks for an attack roll against the goblin's AC, applies your Dexterity modifier and proficiency bonus, and because you were hidden it rolls two d20s and takes the higher. On a hit it rolls your weapon dice plus your sneak attack dice and takes the total off the goblin's hit points.
Later you drop a fireball into a pack of them. The AI checks each target's Dexterity save against your spell save DC, halves the damage on a success, spends the third-level slot, and tracks whether you were concentrating on anything else. Take a hit and get Frightened, Grappled, or Poisoned, and it applies the condition and enforces what it does until it ends. Fall to zero hit points and it runs your death saving throws, roll by roll. You say what your character does. The AI runs the rules underneath.
What the AI GM does
A Game Master that runs fifth edition by the book
The d20 test
Ability checks, attack rolls, and saving throws against a DC, with your proficiency bonus and ability modifiers applied for you.
Advantage and disadvantage
Hidden, prone, poisoned, or aiming true: the AI grants advantage or disadvantage where fifth edition says it should, and rolls the two d20s.
Initiative and the action economy
Combat runs in initiative order, and every turn holds you to one action, a bonus action, a reaction, and your movement.
Spells, slots, and concentration
It spends the right spell slot, tracks concentration, and rolls the saving throws your spells force on their targets.
Conditions and death saves
Blinded, Charmed, Frightened, Grappled, and the rest get applied and enforced. Drop to zero and it runs your death saving throws.
Your full 5e sheet, live
Class, level, ability scores, AC, HP, hit dice, XP, proficiencies, inventory, and spells, updated as you play and as you level up.
Who does what
The AI runs the rules; you make the choices
| The AI Game Master handles | You decide |
|---|---|
| Rolling checks, saves, and attacks, and reading the result | What your character actually does |
| Setting the DC and applying advantage or disadvantage | Which spell, which tactic, which risk |
| Running monsters in initiative order | How you fight, flee, or talk your way out |
| Tracking HP, conditions, spell slots, and death saves | When to rest, push on, or retreat |
| Keeping your character sheet current as you level | The story you want to tell |
Getting started
From zero to rolling initiative in a minute

Switch to 5e so the AI runs fifth edition rules and keeps a full character sheet.
Make your character
Describe who you are, or set race, class, and level. It fills in the modifiers and proficiencies.
Start the adventure
Take an opening scene from the AI or write your own, then say what you do.
Play and level up
Fight, explore, and talk. The AI tracks your XP and walks you through leveling.
The part that lasts
A fifth edition campaign that remembers itself
Most AI games forget. Forty rooms into the dungeon, the name of the NPC who hired you is gone and the plot drifts. Auferet keeps your party, the people you meet, the places you go, and the events that matter in dedicated libraries that stay in front of the AI. Upload a setting bible or your session notes as a PDF and it reads them in. That is what turns a fifth edition one-shot into a campaign that holds up across dozens of sessions.
FAQ
5e with an AI Game Master, answered
Does it use advantage and disadvantage?
Yes. When you are hidden, prone, poisoned, or otherwise set up for it, the AI grants advantage or disadvantage and rolls two d20s, taking the higher or the lower as the rules say.
Does it track a real 5e character sheet?
Yes. Class, level, ability scores, AC, HP, hit dice, XP, proficiency bonus, inventory, and spell slots, all live and updated as you play and level up.
Can it run 5e combat and spellcasting?
Yes. It rolls initiative, holds you to the action economy, resolves attack rolls against AC, forces saving throws against your spell save DC, spends spell slots, and tracks concentration.
Does it handle the 2014 and 2024 rules?
Yes. Both rulesets are supported. The 2024 update is fully compatible with fifth edition, so you can play either one.
Is it free?
You get 10 free credits to claim every day, with every feature. Unlimited actions start at $10/mo. It plays in your browser, and there is an Android app.
Can I play solo?
Solo is the default, just you and the AI Game Master. You can also invite friends into the same game and take turns in real time.
Will it remember a long campaign?
Yes. NPCs, places, and events stay in memory libraries, and you can upload your own lore, so session forty still knows what happened in session one.
Do you also support Pathfinder?
Yes. There is a separate Pathfinder 2e mode with the three-action economy, proficiency ranks, and degrees of success.
Does it track spell slots?
Yes, first through ninth level, each slot marked off as you spend it and restored when you rest. You can see what you have left rather than keeping a tally in your head or trusting the narration to have counted right.
What happens when my character drops to zero?
You go into death saves, three successes against three failures, tracked on the sheet the way the rules run it. Being stabilised, healed, or finished off all resolve properly instead of the story simply deciding you survived.
Can I take a short rest and spend hit dice?
Yes. Your hit dice are tracked with the die type for your class, and a short rest lets you spend them to heal, rolling the die and adding your Constitution modifier per die spent. Spent dice stay spent until a long rest gives them back.
Does it handle concentration?
Yes. Spells that need concentration are tracked as such, so taking damage puts that spell at risk and casting a second concentration spell drops the first. It is one of the easiest things for a general chatbot to quietly ignore, and it changes how casters actually play.
Does it roll initiative and run turn order?
Yes. Initiative sits on the sheet along with armour class, speed and proficiency bonus, and combat runs in order rather than as a single block of narration where everything happens at once.
Do I earn XP and level up?
Yes. Experience is awarded for defeating enemies and completing objectives as you go, so levelling comes out of what you actually did rather than the story deciding you feel more powerful now.
Does it track temporary hit points and inspiration?
Both, along with current and maximum hit points. Temporary hit points are kept separate from your real ones so they absorb damage first and vanish when they should, which is the detail most improvised tracking gets wrong.
