Wizards of the Coast partnered with Voight.ai (also called Artistree) to build a tool that checks whether artwork submitted by freelance artists contains AI-generated elements. The tool is used internally to enforce WotC's ban on AI art in D&D and Magic: The Gathering products.

The partnership was announced June 12, 2024 as an addition to WotC's Generative AI Art FAQ on the official D&D support site. Voight.ai's "Human Certification project" was described as built "alongside artists and creatives" and designed to detect unauthorized AI usage during the asset production process. The tool is used by WotC staff to vet commissioned artwork before publication — it is not consumer-facing. This came after two high-profile incidents (the Glory of the Giants sourcebook and the Ravnica Remastered marketing image) where AI art appeared in WotC products despite stated policy against it.
