Freedom with consequence
Type any action you want — the result becomes durable run state, not a disposable transcript.
Freeform, but it sticks
An AI Dungeon Alternative With Persistent Worlds
Keep the do-anything freedom of a text adventure, but add a world that tracks more than one scene — locations, factions, memories, resources, and saved runs.
For players who love AI Dungeon's freedom but want consequence, persistence, and forgeable, shareable worlds.
AI Dungeon proved that an AI text adventure can go anywhere. Its weakness is what happens after the sentence: pure chat context drifts, forgets, and contradicts itself, because nothing outside the transcript is actually true. Altworld takes the opposite approach — every turn first updates structured world state (characters, factions, resources, rumors, locations, relationships), and only then writes the narration from what really changed.
That difference compounds. In a long AI Dungeon story you eventually manage the AI's memory yourself. In an Altworld run, the debt you took in turn 3 is still on the books in turn 40, the family you angered still holds a grudge, and the rumor you started has either died out or reached the wrong ears. You can also share a world with friends: multiplayer sessions let several players live inside the same persistent world — something classic AI text adventures don't do.
You can try it without an account: guest runs are free for your first ten turns, no sign-up, straight from the browser.
