Nia: Hello Heart's AI Heart Health Chatbot
Nia is Hello Heart’s AI-powered interactive chatbot, built into the Hello Heart app. Nia provides members with general health education, information about their medications, and ongoing support for managing their heart health. It is designed to increase member awareness, education, and empowerment — not to replace clinical care.
What can Nia do, and what can't it do?
Nia can answer general questions about heart health and medications and help members stay engaged between visits. It cannot diagnose, prescribe, or replace a doctor, and it always points members back to a licensed provider for clinical decisions.
What Nia can do:
- Provide general education on cardiovascular health
- Answer medication questions, such as what a medication treats, common side effects, and general usage
- Support members in self-managing their heart health between clinical visits
- Recommend contacting a licensed provider when clinical care may be needed
What Nia will not do:
- Diagnose conditions or predict health outcomes
- Recommend starting, stopping, or changing any medication
- Handle emergencies. If a member describes serious symptoms like chest pain, Nia immediately advises them to seek medical attention
How does Hello Heart keep Nia safe and accurate?
Hello Heart controls how Nia behaves, not the underlying AI models. Every interaction is shaped by Hello Heart's own rules, guardrails, and clinical guidelines, scoped specifically for heart health.
Nia runs on the latest large language models from Anthropic, OpenAI, and Google, and those models are governed by Hello Heart's behavior layer and held to strict security, privacy, and contractual controls.
Hello Heart keeps Nia safe through multiple layers:
- For medication information, responses are drawn from an LLM knowledge base, pressure-tested through Hello Heart's proprietary multi-query process, and reviewed and edited by licensed healthcare providers before members ever see them
- Real-time automated monitoring plus weekly clinical review by Hello Heart's medical affairs team
- Continuous guardrail testing at the product level, such as no harmful content, and the clinical level, such as no prescribing or diagnosis
- An AI Governance Council that requires risk assessments and approval before any new AI capability launches
- Audit logging and incident response plans
Is Nia tested for bias?
Yes. Hello Heart runs ongoing fairness testing across demographic groups to identify and reduce bias in Nia's responses.
How is member data protected, and is it used to train Nia?
No. Hello Heart does not use member data to train Nia. No PHI, PII, or member data was used to train or fine-tune the underlying model. Nia is designed to be HIPAA compliant and built to meet HITRUST standards.
Member data, such as medications or blood pressure readings, is used only during a live session to personalize responses, and it is never retained to develop or train the model.
How member data is secured:
- Encrypted at rest and in transit using AES-256 within US-based AWS cloud infrastructure
- Access is role-based and limited to authorized personnel using the minimum data necessary
- Hello Heart maintains audit trails of all data access
- Hello Heart does not share or sell member personal health information, including anything entered into Nia
Will members know they are talking to AI, and can they opt out?
Yes. Members see a clear AI disclosure before they use Nia, so they always know they are interacting with an AI system and not a human. Members can opt out of AI-assisted recommendations at any time and keep full access to every other Hello Heart service.
Members can always:
- Ask how AI is used in their care
- Request information about what data is being analyzed
- Opt out of AI-assisted recommendations while continuing to use Hello Heart
- Receive Hello Heart's standard service regardless of their choice
Full consent language is available in Hello Heart's privacy policy.
Is Nia a medical device or regulated by the FDA?
No. Nia is not a medical device and is not regulated by the FDA. It does not diagnose conditions, analyze a member's individual clinical data, or recommend treatment, so it falls outside the FDA's definition of a medical device. Nia works only as an educational and self-management support tool.
