Amazon's Health AI is now accessible to all customers in the United States.

      Three years after its $3.9 billion investment in One Medical, Amazon is rolling out its healthcare AI assistant across its main website and shopping app, posing a direct challenge to OpenAI’s ChatGPT Health and Anthropic’s Claude for Healthcare.

      Amazon has made its Health AI assistant available to all US customers, eliminating the requirement to be a One Medical member or a Prime subscriber for access. Previously restricted to the One Medical app, Health AI can now be used via Amazon.com and the Amazon mobile app.

      The assistant can address general health inquiries without consulting a user's personal medical records, but its primary focus is on personalization. Customers who agree to share their health data through the Health Information Exchange—a nationwide system that facilitates the transfer of medical records between providers— can request Health AI to interpret lab results, clarify diagnoses, review medications, and receive advice that considers their individual health histories.

      For Prime subscribers in the US, Amazon is offering a promotional bundle: up to five free direct-message consultations with a One Medical provider for various common conditions, including cold and flu, allergies, acid reflux, pink eye, UTIs, erectile dysfunction, anti-aging skincare, and hair loss. Amazon assesses this value at up to $145 in care. Non-Prime users can connect with One Medical providers on a pay-per-visit basis, priced at $29. Prime members seeking ongoing access can purchase a One Medical membership for $99 annually, instead of the standard $199 rate.

      Health AI operates on Amazon Bedrock, the company's managed AI infrastructure service, and is described in the launch post as utilizing a multi-agent architecture: a primary agent manages patient interactions, sub-agents handle specific clinical tasks, auditor agents monitor conversations in real time, and sentinel agents oversee the entire system with escalation options to human providers.

      Amazon states that the system was tested against artificially generated clinical conversations prior to launch and must meet or exceed clinician-level performance on critical safety decisions before release.

      Amazon emphasizes that Health AI is designed to complement, not replace, the relationship between patients and their doctors. The assistant will direct users to human providers if it lacks certainty regarding clinical recommendations. It explicitly does not aim to diagnose or treat without the involvement of a care provider.

      Privacy is a key focus, and Amazon has been careful to outline its policies, though not in exhaustive detail. All interactions occur within a HIPAA-compliant environment and are secured by encryption and access controls, according to the company. Protected health information from One Medical and Amazon Pharmacy is not utilized for general merchandise marketing or sold to third parties. However, Amazon acknowledges that it trains Health AI on “abstracted patterns” derived from aggregated patient interactions, such as utilizing patterns from various patients querying about medication interactions to enhance future responses, all while preserving individual privacy. The company asserts that this practice is compliant with HIPAA. TechCrunch has requested specific details about encryption and access controls but had not received a response at the time of publication.

      Researchers from institutions like Stanford and Duke have advised caution concerning the sharing of personal health information with AI systems, raising concerns about the use of training data and the reliability of AI-generated health advice.

      These concerns are applicable not only to Amazon but to the entire sector, and they are likely to grow as Health AI expands its user base beyond One Medical members and into the broader population of Amazon shoppers.

      Health AI enters a highly competitive market that is evolving quickly. OpenAI launched ChatGPT Health in January 2026, followed by Anthropic’s Claude for Healthcare a week later. Amazon is now a significant competitor in the race for AI health assistant users.

      Unlike the other two, Amazon benefits from an integrated clinical network, a pharmacy, and an established relationship with hundreds of millions of retail shoppers, providing a distinct advantage in distribution.

      The assistant was co-developed with One Medical’s clinical team and is discussed in the launch post by Prakash Bulusu, CTO of Amazon Health Services, and Dr. Andrew Diamond, Chief Medical Officer of Amazon One Medical.

      Amazon intends to broaden availability to all US customers in the upcoming weeks.
