AI Dungeon

World-building depth is supported through a Lorebook and memory system that persists character traits, world facts, faction rules, and story history across a session.

Users can define the specifics of their fictional universe geography, politics, magic systems, character relationships and the AI references these established facts when generating new content, maintaining internal consistency as stories grow longer and more complex.

An Author's Notes feature and output length controls give players a creative director role over the AI's narrative behavior. Author's Notes allow users to inject background context that shapes how the AI writes tone, genre, perspective, thematic focus without it appearing as direct story text.

This meta-layer of creative control helps experienced storytellers maintain narrative quality over extended sessions.

Multiplayer modes enable co-operative storytelling with other players in shared narrative spaces. Users can invite others to participate in the same ongoing story, contribute actions, and shape the narrative collaboratively, turning AI Dungeon into a shared creative writing space rather than a solitary experience.

A scenario hub allows the community to publish and discover custom story setups, character packs, and world templates created by other players.

AI Dungeon offers a free tier for initial exploration of the platform. Paid plans starting at approximately $9.99 per month provide expanded usage limits and access to multiple frontier AI models including more powerful language models capable of richer, more narratively coherent fiction generation.
