Amazon opens Health AI assistant to all US shoppers

TL;DR:

  • Amazon is rolling out its Health AI assistant on Amazon.com and the main app, removing the previous requirement to use the One Medical app.
  • The tool can interpret lab results, manage prescriptions, and connect users to clinicians, though privacy researchers have flagged risks around sharing medical data with AI systems.
  • The move puts Amazon in direct competition with OpenAI’s ChatGPT Health and Anthropic’s Claude for Healthcare, both launched earlier this year.

Amazon is making its healthcare AI assistant available far beyond its original home. Health AI, which launched exclusively on the One Medical app following Amazon’s $3.9 billion acquisition of the primary care provider in 2023, will now be accessible through the main Amazon website and app.

Users do not need a Prime subscription or One Medical membership to access the assistant, which can field general health queries, explain medical records, handle prescription renewals, and book appointments.

Personalisation and privacy trade-offs

Where Health AI differs from general-purpose chatbots is in its ability to pull a user’s medical history through the Health Information Exchange, the US-wide secure system for sharing patient data. With permission granted, the assistant can contextualise lab results and offer tailored guidance on symptoms and medications.

Amazon states that interactions happen within a HIPAA-compliant environment with encryption and access controls, though the company has not detailed what encryption standards are in use or precisely who can access conversation data. The assistant’s training uses “abstracted patterns” rather than directly identifiable information, according to Amazon.

Privacy researchers have raised broader concerns about AI companies using health-related conversations for model training, a tension that applies across the sector rather than to Amazon alone.

A crowded field gets busier

Prime members receive up to five free message-based consultations with One Medical providers for common conditions. Non-members can pay per visit, giving Amazon a new funnel from AI chat to paid healthcare services.

The timing is notable. OpenAI released ChatGPT Health in January 2026, followed a week later by Anthropic’s Claude for Healthcare. Amazon’s approach differs by tying AI directly into an existing care network rather than offering standalone medical Q&A. For UK observers watching the NHS’s own AI ambitions, the speed at which US tech firms are embedding AI into clinical pathways offers both a benchmark and a cautionary tale about data governance trade-offs.
