In their own words
Cass
Cass is a web-accessible AI mental-health assistant offering wellness chatbot support around the clock. People can use SMS or Facebook Messenger without downloading an app, creating an account, or joining a waitlist. Its knowledge engine covers 800 topics and more than three million variations. Cass offers personalised conversations, recommendations, resources, surveys, guided exercises, follow-ups, goals, referrals, and self-assessments including GAD-7 and PHQ-9. It flags crises, verifies severity, and can engage a crisis professional within 20 seconds. Users may connect on demand with 5,000 coaches across all 50 states, and the service supports seven languages. Cass can be embedded in websites, portals, Google Home, Instagram, WhatsApp, and other channels. It provides an insights dashboard with database or EHR integration. Cass states HIPAA compliance and SOC 2 certification, with encryption and daily server audits, but communications through SMS, Messenger, and WhatsApp are outside HIPAA coverage except Signal.
GiGi
GiGi, also called HeyGiGi, is a web-based mental health education membership focused on practical skills for emotions, relationships, parenting and everyday challenges. Its material includes games, brain science, stories, films, tools, an AI coach and live community experiences. Each day brings a rotating game, a Daily Spark and selected articles, videos or activities. GiGi can converse, recommend content and support structured lessons and role-play; those last two modes are Premium features. Free access includes a game each day, up to three games a week, the first Learning Journey milestone, free articles and videos, and ten GiGi messages a day with an account. Premium adds a full archive, custom Toolkit lists, premium modes, a larger daily message allowance and gems each billing period. The listed plans are Free at free, Premium monthly at $9.99 a month, and Premium annual at $99.99 a year. Conversations are for adults and are not therapy, clinical care, diagnosis or crisis support. Signed-in conversations are stored until deleted and sent to an AI provider contractually barred from training on them.
