Therapist AI refers to artificial intelligence technology designed to simulate supportive, therapy-style conversations and provide structured mental wellness guidance. Using advanced natural language processing and machine learning, therapist AI systems can understand user input, detect emotional patterns, and respond with empathetic, thoughtful dialogue. These platforms often incorporate psychology-based techniques such as cognitive behavioral therapy (CBT) prompts, mindfulness exercises, grounding strategies, and reflective questioning to help users manage stress, anxiety, overthinking, and everyday emotional struggles.
