Cass
What it is
Cass is a free, web-based AI mental-health assistant that offers wellness chatbot support around the clock. People can use SMS or Facebook Messenger without downloading an app or creating an account. Cass provides personalized conversations, recommendations, resources, surveys, guided exercises, follow-ups, goals and referrals, and can administer self-assessments such as GAD-7 and PHQ-9. Its knowledge engine covers 800 topics and more than 3 million variations. The service flags crisis situations, verifies severity and engages a crisis professional within 20 seconds, while stating that it is not a crisis-response service or a replacement for professional therapy. Users can connect on demand with 5,000 coaches across all 50 states, and Cass supports seven languages including English and Spanish. It can be embedded in channels such as Google Home, Instagram, WhatsApp and websites. Cass states HIPAA compliance on its network and SOC 2 certification; SMS, Messenger and WhatsApp are outside that coverage except Signal. Data deletion requests are supported.
