Cass

Overview

Cass offers round-the-clock wellness chatbot support, with personalized conversations, recommendations, follow-ups, and referrals. Users can start by text or Facebook Messenger without downloading an app or creating an account, which makes access straightforward for people who do not want another app or sign-up process.

Its scope is broader than a chatbot alone: it can administer GAD-7 and PHQ-9 self-assessments, set goals, deliver surveys and exercises, and connect users on demand to a network of 5,000 coaches across all 50 states. Cass says its knowledge engine spans 800 topics and more than 3 million variations. That breadth supports varied conversations, though the product itself says it is not a crisis-response service or a replacement for professional therapy.

Key features

Coaching and assessments

Cass combines conversational coaching with self-guided exercises, goal setting, resources, and follow-up. GAD-7 and PHQ-9 assessments give users a structured way to reflect on symptoms; they should not be mistaken for diagnosis. The option to refer users to a coach is a meaningful bridge to human support when automated guidance is not enough.

Access, integrations, and privacy

Alongside SMS and Facebook Messenger, Cass can be embedded in Google Home, Instagram, WhatsApp, websites, portals, and other communication channels. It supports seven languages, including English and Spanish, and provides an insights dashboard with reporting and the ability to integrate information into a database or EHR. These features make it relevant to organizations as well as individuals.

Cass says it is HIPAA-compliant and SOC 2 certified, encrypts data with at least 256-bit asymmetric or 4096-bit symmetric keys, and secures transit with TLS 1.2 and 1.3. It also says users can request deletion of their data at any point. The HIPAA boundary matters: Cass says its compliance applies on its own network, while SMS, Facebook Messenger, and WhatsApp communications are not covered, except Signal.

Crisis limits

Cass says it flags crisis situations, verifies severity, and engages a crisis professional within 20 seconds. That escalation is a useful safeguard, but it does not make Cass a crisis service; people in immediate danger should seek emergency help rather than rely on the chatbot.

Pricing

Cass has a free plan, but its published plan prices are also aimed at organizational deployment. The At-scale employee plan costs 0.05 USD per year, billed per employee per year at scale. It suits employers pricing access across a workforce, but the per-employee-at-scale terms make it a poor basis for assuming a small deployment will cost the same.

The Active user plan costs 5.00 USD per month, billed per person, with 24/7 access. It is the clearer fit when an organization wants to pay for active users rather than all employees. No seat minimum, usage quota, trial, or renewal term is established for either plan. Individual access is free, but the free plan's caps are not established.

Platforms

Cass is listed for web access and also reaches users through text messaging and Facebook Messenger without an app download or account. Its integrations extend to Google Home, Instagram, WhatsApp, websites, and portals. Messaging-channel access comes with the privacy caveat that SMS, Facebook Messenger, and WhatsApp are outside Cass's stated HIPAA coverage, except Signal.

Who it's for

Cass is a good fit for individuals seeking accessible wellness coaching, self-assessments, and exercises, especially those who prefer messaging to installing an app. Its coach network and organizational reporting also suit health plans, providers, employers, and communities planning broader access. It is not the right choice for someone seeking therapy, a diagnosis, or crisis response from an app.

Pros and cons

• Pro: SMS access without an app, account, or waitlist lowers barriers to getting started.
• Pro: Assessments, exercises, follow-ups, and referrals combine self-guided support with a path to human coaching.
• Pro: Seven languages and integrations with organizational systems support wider deployment.
• Con: HIPAA coverage does not extend to several prominent messaging channels, including SMS and Facebook Messenger.
• Con: Cass is not a substitute for therapy or crisis response, limiting its role for people who need clinical care or urgent intervention.
• Con: The employee plan's scale-based pricing and the active-user charge require organizations to match the plan to their deployment model.

Alternatives

For a broader comparison, see AI Mental Health Chatbots. Choose Noa by Anshap if you want core features at no cost across Android, iOS, and web, without paywalls or hidden fees. Thrive AI suits Android or iOS users who want a free chatbot, blogs, and self-assessments, with AI-guided exercises excluded from its free plan.

Dr. Riya by Mindtalk is another free option across Android, iOS, and web; it does not provide diagnosis, prescribing, or therapy. Elomia is an alternative for users considering an individual subscription, with monthly pricing that varies by option. For CBT materials, CBT without a Therapist: Helpy offers a free thought journal, exercise library, and first course modules, while limiting AI chat replies.

Clare may suit users who prefer calls and messages during set daily hours; its free access runs 9 am–5 pm in the user's local time. Alongside is a paid alternative for people open to a paid service. Mentis offers tracking, articles, journaling, CBT activities, and a limited AI plan on its free tier for Android and iOS users.

Verdict

Choose Cass if you want messaging-first wellness coaching, structured self-assessments, and a route to human coaches without installing an app. Its breadth and access options are compelling for individuals and organizations, but its therapy and crisis limits—and the privacy boundary around common messaging channels—are reasons to look elsewhere when clinical care, urgent support, or covered communications are priorities.
