AI Dungeon

AI Dungeon is a text adventure game in which the story is generated as it is played. A player sets a premise, types what their character does next and the model writes the consequence, so the plot is open ended rather than drawn from a fixed script. It runs in a browser and in mobile applications, and is published by Latitude. Players can begin with a prepared scenario such as a fantasy quest or a collapsed future world, build a custom scenario of their own, or join adventures published by other players. The game keeps memories that persist across a session so established facts about characters and places are carried forward, and it supports image generation alongside the text. Membership tiers differ in the models available, the amount of context the model can hold, the number of memories retained and the monthly credit allowance used for images or temporary context expansion. Five tiers are published. Wanderer is free, with 25 memories and a 4k token context. Journey is $14.99 per month with 760 credits, 100 memories and 8k of context. Legend is $29.99 per month with 1,650 credits, 200 memories and 16k of context. Mythic is $49.99 per month with 2,750 credits, 400 memories and 32k of context. Ultimate is $99.99 per month with 5,200 credits and 800 memories. Subscriptions run month to month or on six or twelve month terms, with discounts on the longer commitments, and the Journey and Legend tiers include a one week trial with purchase. The documentation notes that an older Adventurer tier is deprecated but still honored for existing subscribers.
