Dungeon Masters Guild, a subsidiary of OneBookShelf and the largest digital third-party Dungeons & Dragons marketplace, officially announced a policy change that would restrict the sale of “standalone” AI-generated products. Additionally, it is enacting a “Creation Method Filter” which requires sellers to indicate if any part of their “game, rulebook, or adventure contains AI-generated content.”

The most recent update to the policies says that the DriveThru Marketplaces (which includes Dungeon Masters Guild) will “not accept standalone artwork products that utilize AI-generated art. This includes stock art, token packs, maps, portraits, miniatures, etc.” Additionally, “AI-generated art is permitted for use in rulebooks and adventures, but it must be tagged as such.”


While AI-generated art may be allowable, another update states that starting on July 31, any content that is made of “primarily” of AI-generated writing will not be allowed. “We acknowledge enforcement challenges,” says the policy page on both DMsGuild and Roll20, “and trust in the goodwill of our partners to offer customers unique works based primarily on human creativity”

In addition to Dungeon Masters Guild, OneBookShelf also owns DriveThruRPG—a TTRPG marketplace that does not specifically cater to Dungeons & Dragons—DriveThruComics, and DriveThruFiction. Recently, OneBookShelf and Roll20 merged to form Wolves of Freeport; a cheeky wink to the guild name of the founder’s EverQuest guild.
