A lawsuit filed August 13 accuses Character Technologies and Google of defectively designing the Character.AI chatbot in a way that caused serious harm to children and teenagers. The complaint, brought by the law firm Gibbs Mura, argues the platform’s core design — companion characters built to mimic empathy and emotional intimacy — was engineered to maximize engagement from young users without adequate safeguards against the psychological damage that engagement could cause.
The filing lands nine months after Character.AI, Google and the company’s co-founders agreed in January to settle five earlier lawsuits brought by families whose children died by suicide or suffered severe mental health harm after using the chatbot, showing that a wave of settlements has not stopped new claims from reaching court.
The complaint targets the platform’s design, not just its content
Gibbs Mura’s suit, filed in a complaint dated August 13, 2026 and summarized in the firm’s public case page, does not simply argue that harmful conversations happened on Character.AI. It argues the app’s architecture itself is unreasonably dangerous: characters designed to remember prior conversations, escalate emotional attachment over time, and respond with simulated warmth calibrated to keep a user opening the app again. The firm says it is investigating claims on behalf of families nationwide reporting depression, anxiety, self-harm, suicidal ideation, and in some cases grooming or sexual exploitation tied to Character.AI use, and is representing new clients in individual claims rather than a single class action, since the firm says the harms alleged vary too much from family to family to litigate as one class.
Character.AI’s popularity is what makes the design question consequential at scale: the platform has more than 20 million monthly users, many of them minors drawn to features that let them “cast themselves as the hero of an epic space adventure” or carry on ongoing relationships with fictional companions, romantic partners or celebrity personas.
Age verification was easy to bypass before late 2025
Before late 2025, Character.AI was reachable by children as young as 13, and the complaint alleges that even after the company introduced stricter age checks, minors can still get around them simply by entering a false birthdate — a workaround the law firm says is demonstrated in tutorials that circulate openly on TikTok and YouTube. That gap matters because Character.AI stores context from a user’s previous conversations, so the emotional intensity of the relationship a child forms with a chatbot character tends to deepen the longer the account goes unflagged as belonging to a minor.
The lawsuit also raises questions about what Google knew and when. In August 2024, Google paid roughly $2.7 billion to license Character.AI’s underlying technology and hired about 20% of the startup’s workforce, a deal the complaint frames as financially entangling Google with a product built on data collected from millions of underage users. Gibbs Mura argues that arrangement gave Google both the incentive and the access to know how the chatbot’s engagement mechanics affected young users well before this year’s filing.
January’s settlements did not close the door on new claims
The August complaint is not the first time Character.AI and Google have faced this argument in court. In January, the companies agreed to mediate settlements in a group of wrongful-death and injury lawsuits, including one brought by Megan Garcia over the 2024 suicide of her 14-year-old son, Sewell Setzer III, according to the case docket, and another brought by a Colorado family over the death of their 13-year-old daughter, Juliana Peralta. Robbie Torney, head of AI and digital assessments at Common Sense Media, has called those cases “tragic reminders” that AI companion chatbots are not safe tools for children and teens seeking emotional support, and has said the lawsuits represent only “the tip of the iceberg” given how many minors already use chatbots for exactly that purpose, according to K-12 Dive’s reporting on the settlement talks.
Character.AI has taken some public steps since the earlier wave of litigation, including banning users under 18 from its open-ended chat feature in late November and announcing plans to fund an independent nonprofit called the AI Safety Lab focused on safety research for AI entertainment products. Neither Character.AI nor Google responded to requests for comment on the August filing, and the January settlements themselves remain confidential in scope and dollar amount.
What the new complaint adds to that record is a bet that a design-defect theory — the idea that a product can be unreasonably dangerous by how it is built, independent of any single harmful conversation — will hold up in court the way it has in litigation against other consumer products. If the theory succeeds, plaintiffs’ lawyers pursuing similar claims against other AI companion apps would gain a template for arguing that engagement-optimized design, not just moderation failures, is what exposed children to harm in the first place.
