A lawsuit has been filed against California-based Character Technologies Inc. in a Texas federal court, alleging its AI chat program is causing serious harm to children and the plaintiffs' families.

In one case, A.R.—an Upshur County resident and mother of J.F., a 17-year-old autistic boy—alleges the Character AI or C.AI app was downloaded by her son without her knowledge because it has a "safe for minors" rating that evaded her parental controls.
