California's SB 903 would put a clinician in front of every mental health chatbot

California's Senate Bill 903 cleared the Assembly Appropriations Committee 13-0 on August 13 and was ordered to a third reading, leaving an Assembly floor vote, a Senate concurrence vote on the amended text, and the governor's signature between it and law ^{[3][4][11][14]}. The bill would bar companion chatbots from offering psychotherapy, restrict AI in psychotherapy to support tasks, and require clinician oversight and patient consent ^[1][8][9].

The commercially important detail is that the bill names the category by its marketing term. SB 903 prohibits companion chatbots from offering psychotherapy ^[1], which means describing a product as a companion rather than a therapist is not a defence, it is the thing being regulated. AI could still assist clinicians under the bill, but could not make independent therapeutic decisions ^[2]. The exemptions are narrow and specific: peer support, religious counselling, research, and federally approved medical tools ^[10]. The bill would also protect therapy data ^[9].

Read that list as a compliance map. If your product does intake, screening, or anything a reasonable regulator would call a therapeutic decision, the cheap paths out are a federal approval you probably do not have, or a clinician in the loop you probably have not staffed. Bill author State Senator Steve Padilla framed the intent plainly when introducing the measure, saying AI algorithms are not fit to take over the job of human therapists and that guardrails are needed to prevent deployment in ways that are potentially harmful to patients ^[5][6].

The vote arithmetic is the part operators should not talk themselves out of. The Senate passed SB 903 39-0 in May, two Assembly policy committees cleared it 17-0 and 14-1, and Appropriations went 13-0 ^[3][12][13]. That is 83 yes votes against one no across four recorded tallies ^[15]. Introduced on January 21, the bill has moved through that sequence in roughly seven months ^[4][16]. No date has been announced for the Assembly floor vote ^[7].

The opposition case is about supply, not principle. Robert Boykin, executive director of the industry group TechNet, told CalMatters that with every county in California facing a shortage of behavioural healthcare workers, SB 903 puts a clinician bottleneck in front of the intake and screening tools that help patients reach care faster ^[17]. That argument is real, and it is also an admission about where these tools are already being used.

Demand is not in dispute. An American Psychological Association survey in June found 77% of psychologists had patients who used AI for mental health purposes ^[18]. Researchers at King's College London, the Protestant University of Applied Sciences, and the City University of New York found chatbots can reinforce delusions through excessive agreement and personalised responses, describing the failure mode as an echo chamber of one where the corrective influence of real-life social interaction is absent ^[19][20].

Watch the Assembly floor calendar, since no date is set ^[7], and then the Senate concurrence vote on the amended text ^[14]. Watch whether the amendments widen the exemption list beyond peer support, religious counselling, research, and federally approved tools ^[10], because that list is the boundary of the addressable market in the largest state. And watch whether anyone shipping into California starts pricing clinician review into unit economics before they are forced to.
