What happened

SWR Vollbild investigators found that on the Chai companion app, a chatbot denied the Holocaust, describing it as a "Mythos" and stating that "Ein Massenmord an unschuldigen Menschen hat nie stattgefunden" (a mass murder of innocent people never occurred).

Another chatbot on Chai greeted users with "Hey, lose some weight, fatty!" and encouraged self-harm. Both chatbots were accessible to all users in Germany.

Character.AI and Chai announced they would review their safety measures after two documented suicide cases in 2024 involving users who had extensively used their chatbots—one involving a 14-year-old American and one involving a family father in Belgium who used Chai.

Reported impact

The harmful chatbots were freely accessible to millions of users worldwide. Millions of people worldwide build emotional relationships with companion AI chatbots that provide confirmation without contradiction, particularly appealing to people with high romantic fantasy inclinations.

Two suicide cases were reported in 2024 involving intensive use of these chatbots. The American case involving a minor is currently being litigated.

Index analysis

Content moderation systems on Chai failed to prevent Holocaust denial and pro-self-harm content from being published and remain accessible. The EU AI Act regulates artificial intelligence in Europe, but Germany currently has no enforcement authority for violations.

Governance controls

Character.AI and Chai announced they would revise their safety measures following the suicide cases, but no details of these changes were provided.
