AI-powered mental wellness application sequence diagram maps user interactions across four core phases: chat therapy sessions with AI service integration, guided wellness activities, journaling with AI-generated insights, and support feedback loops. The architecture demonstrates asynchronous API calls between the web application frontend and external AI services, with numbered interaction steps showing request-response patterns for each phase. This pattern is essential for architects building HIPAA-compliant telehealth platforms requiring conversational AI, session persistence, and user engagement tracking. Fork this diagram on Diagrams.so to customize interaction flows, add authentication layers, or integrate specific AI providers like OpenAI or Azure Cognitive Services. Ideal for prototyping mental health SaaS products where user experience and data privacy are paramount.
