CBT Catalyst is a GPT designed and offered by CareClinic.io. As its name indicates, the GPT is meant to serve as a companion, guiding users in the use of Cognitive Behavioral Therapy (CBT). CBT is a form of psychological treatment that has been demonstrated to be effective for a range of problems including depression, anxiety disorders, alcohol and drug use problems, marital problems, eating disorders, and severe mental illness. GPTs are like applications that operate on top of ChatGPT, and in this case, CBT Catalyst leverages the technology to assist those seeking guidance about CBT. The application provides a platform where users can seek information and advice about managing stress, dealing with negative thoughts, or what steps to take when feeling anxious. It commences with a welcome message to the user asking how assistance can be provided. The GPT has been programmed with a variety of prompt starters like 'What is CBT?', 'How can I manage stress?', 'How can I deal with overwhelming negative thoughts?', and 'What can I do if I start feeling anxious?', which illustrate the thematic range it can cover. However, an important point to note is that access to CBT Catalyst requires subscription to ChatGPT Plus. The tool is thus particularly suitable for individuals looking for AI-oriented mental health support, especially in the context of CBT.
