What is ChatGPT Health, and how is it different from an AI doctor?

What is ChatGPT Health?

OpenAI introduced ChatGPT Health on January 7, 2026, as a dedicated health experience inside ChatGPT, first for a small group of early users. On July 23, 2026, OpenAI announced it was rolling Health out to US users 18 and older.

The core idea is connecting your own data. OpenAI says you can link Apple Health, supported medical records from US hospital systems, One Medical, and Function Health. Then you can ask ChatGPT to compare a new lab result with older ones, summarize what changed since your last appointment, or look at how sleep and activity relate to your routine. Wearables and apps like Oura, Whoop, Garmin, and Strava reach ChatGPT through Apple Health, so sharing to Apple Health has to be turned on first. OpenAI's help center also says ChatGPT may send proactive updates, for example when new medical records sync.

OpenAI is clear about the limits. It says Health is designed to support, not replace, medical care, is not intended for diagnosis or treatment, and that for urgent symptoms or emergencies you should seek immediate professional help.

• Started: January 7, 2026, wider US rollout from July 23, 2026
• Connects: Apple Health (iPhone only), supported US provider portals, One Medical, Function Health
• Read only: ChatGPT cannot change your records or write back to Apple Health
• Not for: diagnosis or treatment, per OpenAI

Is ChatGPT Health free?

Yes, with an account. OpenAI's help center says Health is available to eligible, logged-in ChatGPT Free, Go, Plus, and Pro users in the US who are 18 or older. It works on the web and the iOS app, and OpenAI says the rollout is gradual, so some eligible people may not see it yet.

What you pay for changes the model, not access. At the July launch, OpenAI said GPT-5.5 Instant was available on the Free plan and that GPT-5.6 Sol, for paid users, was its strongest model yet for health. OpenAI has released newer models since, so check which model your plan uses.

A few things to know before you start: you need to sign in, Apple Health needs an iPhone, and OpenAI lists only web and iOS as supported.

What does ChatGPT Health do with your data?

OpenAI says connected medical records and Apple Health data, and the conversations that use them, are not used to train its foundation models or to target ads, whatever your training setting. Chats that don't use that data follow your normal ChatGPT training setting.

You control when ChatGPT can use connected data, in Settings, Plugins, Health. Since September 2026, OpenAI says new Health connections follow your general plugin permission setting, which is "Allow low-risk actions" unless you change it, so check that setting if you want ChatGPT to ask first. If you disconnect an account, OpenAI says synced data is deleted from its systems within 30 days, but anything already in your chat history stays until you delete those chats. Health conversations can create memories when memory is on.

OpenAI also says Health is not intended for clinical or covered-entity use and does not offer a Business Associate Agreement. For HIPAA-covered providers and insurers, OpenAI points to separate products, ChatGPT for Healthcare and ChatGPT for Clinicians.

How is an AI doctor you text different?

ChatGPT Health starts from your data: it helps you read what is already in your records and apps. An AI doctor you text starts from your symptom: it asks the questions a clinician would ask, then tells you what to do and how soon. The line is not absolute: OpenAI says its health models are trained to ask for missing context and recognize when professional care may be needed.

Pymander is the second kind. You text it like a person, with no app to download and no account to make. It asks follow-up questions, gives you a plan, tells you when to see a clinician or get emergency care, and remembers your history between visits. Pymander is top five on HealthBench Hard and scored 98.2% on the USMLE. It is a medical AI system, not a licensed doctor, and it does not prescribe.

ChatGPT Health vs Pymander vs other options: which fits?

Pick by the job. Here is what each option is good for.

• Pymander (our pick for most people): free, by text, no app, no account, no insurance, 24/7 for adults in the US. Asks follow-up questions, gives a plan, tells you when to get care, remembers your history. Top five on HealthBench Hard and 98.2% on the USMLE. Not a licensed doctor, does not prescribe.
• ChatGPT Health: free on the Free plan for logged-in US adults on web and iOS. Best when the answer depends on records you already have: lab trends, visit notes, appointment prep, sleep and activity data. Needs an account, and OpenAI says it is not for diagnosis or treatment.
• Plain ChatGPT, no Health connected: OpenAI says you can ask health questions without connecting anything. Good for learning about a condition or a test. Without connected data, it works from what you tell it.
• A licensed clinician (your doctor, telehealth, urgent care): the option when you need an exam, a test, a diagnosis, or a prescription. Costs and wait times vary by plan and service.

Can you use both?

Yes, and many people will. A simple split: text an AI doctor when something new is going on and you want to know how worried to be tonight, and use ChatGPT Health when you want to understand a lab report or prepare questions for a visit.

Whatever you use, OpenAI's advice for ChatGPT is a good rule for any AI tool: verify important information and discuss medical decisions with your healthcare provider. If you want to compare general chatbots, we cover Gemini vs ChatGPT and Claude vs ChatGPT for health on separate pages.
