AI Therapists are advanced applications, often powered by LLMs, that provide mental health support through conversational interfaces. These digital tools offer a confidential and accessible space for users to discuss their thoughts and feelings. They can guide users through cognitive-behavioral therapy (CBT) exercises, teach mindfulness techniques, and provide empathetic responses to help manage conditions like anxiety and depression. While not a substitute for human therapists, AI therapy bots can serve as a valuable supplement, offering 24/7 support and helping to reduce the stigma associated with seeking mental health care.
