Rolegend and AI Dungeon

AI Dungeon is the better place to tell any story you like. Rolegend is the better place to play a fifth edition character, alone or with friends, with real numbers and a Virtual Tabletop.

Every claim about AI Dungeon below links to the page it was read on. Most recent check: .
Vaelantir: the timbered inn and walled gate of Karth's Hold on a rocky bluff, torches lit at dusk, with travelers and pack mules at the door. To the left, ivied imperial ruins rise from a misted valley, and a dragon crosses an overcast sky.

What AI Dungeon is

AI Dungeon is the original AI text adventure: you type what you do, the AI writes what happens, and the story can go anywhere in any genre. It has a decade of tooling built around keeping a long story coherent (Story Cards, Plot Components, a Memory Bank, selectable models, scenario scripting), plus multiplayer and a large library of community-made scenarios. It is a storytelling engine, and it says so; mechanics are something a scenario author can add rather than something the platform runs.

What we could verify

  • AI Dungeon's homepage describes it as a free AI text adventure game where players create open-ended stories, explore interactive worlds and guide every choice. (source, checked )
  • A turn is taken with one of four action types: Do performs an action, Say speaks a line, Story writes narration directly, and See generates an image. (source, checked )
  • Coherence is guided by Plot Components. Plot Essentials holds the story details that stay relevant throughout, and the Author's Note carries genre, writing style and tone instructions. (source, checked )
  • Story Cards are notes for the AI about characters, locations and concepts. They enter the context only when their Trigger keywords appear in the input or output, and stay active for a variable period depending on context size. (source, checked )
  • The new player guide lists simulating dice rolls among the effects of Scripts. The creator of a Scenario can add Scripts to it, and a player can find Scripts on Discover and add them to an ongoing Adventure. (source, checked )
  • Scenarios are templates a player starts a new Adventure from, carrying the Plot Essentials, Story Cards and other settings across to the new Adventure. (source, checked )
  • Content can be Private, Unlisted or Published. Published content is public and available for anyone online to see, read or play. (source, checked )
  • Multiplayer is supported, there is no set limit on how many people can join a game, and players join using an eight-digit code from the Invite Players menu. (source, checked )
  • Players choose which language model runs their Adventure from a published list of more than twenty current models, documented model by model. (source, checked )
  • See mode lets a player create and add images to an Adventure during gameplay, from a text prompt typed in the input bar. (source, checked )

What AI Dungeon does better

  • Open-ended, system-free storytelling. AI Dungeon started this category and is still the best thing available for it. Any genre, any premise, no character sheet in the way.
  • Big groups. Multiplayer is a first-class feature with no documented cap on players.
  • Starting from somebody else's idea. A large published library of community-made scenarios means you can be inside a world in seconds.
  • Choosing your own model. More than twenty selectable models, with a published breakdown of how they differ.
  • Being extended. Scenario scripting in JavaScript can reach into the input, the model context and the output, so an author can build mechanics AI Dungeon does not ship, including dice.
  • Length and looseness. Nothing in the design objects if the story wanders into a different genre, century or planet halfway through.

What Rolegend does differently

  • Keystone Engine is a game engine, built apart from the AI. It handles the dice and the game state. Every roll, modifier, hit point, condition, spell slot and item is settled before ROWAN writes a word, and ROWAN gets on with the story. ROWAN cannot change a number or roll again. When your character acts, the game hands you the die to roll, and Keystone Engine adds the modifiers from your sheet.
  • Your character sheet and the world are stored as structured data, not text the model has to remember, so nothing drifts over a long campaign.
  • Rolegend's Keystone Engine can support any system. Fifth edition is the system it plays today, built from the System Reference Document.
  • Play with friends or solo. A paid host seats up to 6 players at one table, the host included, and friends on the free plan can join. Each player plays their own character. When everyone is online you can play live, and the table updates every few seconds. When they are not, play async play-by-post and drop in whenever you want. In a fight each player acts on their character's turn, and an email says when the table waits for you. Alone, the paid party holds up to 6 characters that you play yourself, and the Game Master plays the companions who join you on the road; the free plan is a single character. The host picks the language that the Game Master narrates in, its tone and the length of its replies.
  • Rolegend's Virtual Tabletop puts a fight on a battle map, with a token for every hero and every enemy, and you drag yours to move. Keystone Engine enforces movement, difficult terrain, cover, line of sight, opportunity attacks, flanking, weapon ranges and light there, and the fog of war hides anything your character cannot see. Every player at the table moves on the same map. Between fights, the map shows the region and the lay of the land in each place. A quick scuffle can also stay in the story, with no map at all.
  • On the paid plan, any Game Master turn can be read aloud, with a narrator voice and a voice of its own for each character who speaks, and you can turn on reading each new reply aloud. One click paints a scene image for a turn or a portrait of your character. You can dictate your own turn on either plan, in a browser with speech recognition (Chrome, Edge and Safari).
  • Async play-by-post. Write a turn at lunch, read the answer at midnight, leave it a week and pick it up mid-scene.

Pick AI Dungeon if

  • You want to tell a story, not play a game with rules. If a die roll saying no would spoil the thing you came for, AI Dungeon is the right product.
  • You want a group bigger than 6.
  • Your setting is not fantasy, or not only fantasy: science fiction, horror, romance and detective stories, all at once.
  • You like browsing. Thousands of published scenarios written by other players is a different way to start.
  • You want to build the mechanics yourself. Scenario scripting is real programmability, and you would enjoy writing your own dice system.

Pick Rolegend if

  • You want to play fifth edition, with a real character sheet, and you want the numbers right without checking them.
  • You want failure to mean something. The roll happens before any narration exists, so the story has to live with it.
  • You want to play with friends who drop in whenever they want, or alone at your own pace.
  • You want grid tactics with teeth. On the Virtual Tabletop the engine enforces movement, cover, line of sight, opportunity attacks, flanking and weapon ranges, and a wall stops a fireball.
  • You want to pick a campaign up in fifteen minutes at midnight and find the world exactly where you left it.
