An AI RPG that plays like a tabletop game
Rolegend is a tabletop roleplaying game with an AI Game Master. You write what your character does, real dice settle what happens, and the AI tells the story of the result. It plays D&D 5e, alone or with friends.
Four different things are called an AI RPG
Search for an AI RPG and you find four kinds of product under the same name. They answer different wants, so it helps to sort them before you choose.
- Story generators. You write a line, and the AI writes the next part of the story. Anything can happen, and nothing has a cost. AI Dungeon is the best known.
- Character chat. You talk to one character that the AI plays. It is a conversation more than a game.
- Video games with AI characters. A normal computer game, where some people in the world answer you in their own words.
- Tabletop RPGs with an AI Game Master. The game of Dungeons & Dragons, with dice, a character sheet and rules, where the AI takes the chair that a person usually sits in.
Rolegend is the fourth kind. If you want the first kind, our page on alternatives to AI Dungeon is an honest map of that ground, and it says where a story generator is the better pick.
What a tabletop game keeps that a story game drops
The difference is not the writing. A good story generator writes well. The difference is what stands behind the words.
In a tabletop game, your character is a set of facts. A fighter has a number of hit points, an armour class, a sword and a set of skills. When the fighter jumps a gap, the rules say which skill applies and how hard the jump is, and a die says if the jump works. A fall costs hit points, and those hit points stay gone until the fighter rests. So a choice has a cost, and a win means something, because a loss was possible.
A story generator has none of those facts. Your character is what the last few paragraphs say about them. That is freedom, and it is also why a story generator cannot give you a fair fight: there is nothing for the fight to be fair about.
Who holds the facts
An AI model is good at words and poor at keeping a number the same for three hundred turns. So Rolegend splits the job in two.
Keystone Engine is a game engine that runs apart from the AI model. It holds every fact of the game: your sheet, your inventory, your conditions, the monsters, the clock and the dice. ROWAN, our narrator, reads those facts and writes the story. ROWAN plays every person you meet and describes every place you go. It cannot change a fact. When it has a goblin attack you, the engine rolls the attack and applies any damage by the rules.
That split is why a month away costs you nothing. Your sheet and the state of the world are stored data, not a memory the AI has to keep.
One turn, from your words to the result
A turn on Rolegend starts with a sentence. You write what your character does, in plain English, as long or as short as you like: "I climb the wall and look over before anybody on the other side sees me."
The game asks for what that needs. Here it is two checks, Athletics to climb and Stealth to stay unseen. Each roll waits for you, and you press the die. The engine adds your modifiers from your sheet and records each total. Then ROWAN writes what you see from the top of the wall, and it knows from the result if a guard looked up.
You never need to know which skill a climb uses. The game knows the rules, so you can learn them as you play, or never.
Alone, or a table of friends
You can play the whole game alone. You make a character, or take one that is ready to play. You can play a whole party of characters yourself, and ROWAN plays the companions who join you on the road.
You can also send friends a link. A table seats up to 6 players, each with a character of their own, in one campaign. When everyone is online, you play live. When nobody is, it plays as play-by-post, one turn at a time, as each of you finds a moment.
What it plays today
Today, every campaign on Rolegend plays D&D 5e, from the free rules of the System Reference Document. Each campaign is written ahead of time, with a story in acts and a world with places of its own. The AI tells that story with you. It does not invent the campaign as it goes.
When a story game is the better choice
Pick a story generator if you want no rules at all: to play a dragon one turn and a starship the next, with nothing in the way. Pick Rolegend if you want the dice to matter, your sheet to be true and your choices to have weight.

Questions
Do I need to know the D&D rules to play?
No, and you will not have to look anything up. You play in your own words, such as "I try to talk her down" or "I go through the desk", and ROWAN works out what that means. If it needs a roll, you roll your own die and Keystone Engine adds the modifiers from your sheet.
You can start from a ready-made character, so your first turn is two sentences rather than an hour of character creation. Everything underneath, such as your bonuses, your hit points and what your spells do, is applied for you as you play. Knowing fifth edition will get you more out of it. It is not a requirement, and this is a reasonable way to learn it.
How is this different from playing D&D with ChatGPT?
In a chat window, the same thing that writes the story also writes the numbers. So a roll is whatever the sentence needed it to be, and asking again nicely tends to produce a better one.
Here those are two different systems. You roll your own die, andKeystone adds the modifiers from your sheet before any narration exists. ROWAN gets the result and has to live with it. Your character sheet works the same way: hit points, gold, conditions and quests are stored and updated, not held in a conversation that has to keep remembering them. Nothing quietly drops your shield forty turns in.
A chat window also only knows what still fits in it. Every turn you have played here is searched by meaning instead, so a detail from a session weeks ago is put back in front of ROWAN in the words you used. It does not survive only if a summary happened to keep it.
Can the AI Game Master cheat on a dice roll?
Not on the number. ROWAN never touches the dice. Keystone hands you the die, adds up your bonuses off your sheet, and records the result before a single word of the reply is written.
ROWAN chooses how a result reads, gently or hard, as the story needs. It cannot turn a 4 into a 19, and it cannot decide after the fact that the lock was easier than it said.
What happens if I do not play for a few weeks?
Nothing at all. There is no streak to break, no daily allowance and no session that expires. You end a session when you decide to, and ending one writes a recap ROWAN carries into the next. Come back in March and your hit points, your gold and your open quests are exactly where you left them.
