A quick note
We discourage the use of medical apps that are not compliant with HIPAA, a U.S. federal law designed to protect sensitive patient health information from being disclosed without consent. Unfortunately, most of the health-related apps in your smartphone's app store are not HIPAA compliant and should be avoided. However, if your healthcare provider offers an online portal, it is almost certainly HIPAA compliant. Your health data also resides in this portal, making it the ideal spot for an AI healthcare assistant. For this reason, we're focusing on the AI features available in online portals now and in the near future. It's actually quite exciting!
The companies that run your doctor's health portal
If you have ever logged in to a patient portal to check a test result, message your doctor, or schedule an appointment, you have used software built by one of a small number of companies. Most people do not know the name behind the app their hospital or clinic uses. But four companies handle a remarkable share of U.S. medical records, and they are all racing to add AI to the patient-facing side of their software.
Epic Systems is the largest, holding records for more than half of all U.S. hospital beds and running MyChart, one of the most widely used health apps in the country. Oracle Health, formerly known as Cerner, is the second largest. Athenahealth operates primarily in outpatient and primary care settings and reaches roughly one in five Americans through the practices it serves. MEDITECH serves many community and rural hospitals, making it important even if it gets less attention than the others.
These companies matter because your doctor’s online portal is likely built by one of them.
What AI can do inside these apps right now
The most mature example of patient-facing AI in a health app today is Epic's Emmie, a conversational assistant built into MyChart. As of early 2026, Emmie can help patients schedule appointments, review billing, set up payment plans, and work through pre-visit tasks like medication review and document signing. Epic also runs a tool called In-Basket ART (Augmented Response Technology), which automatically drafts responses to patient messages sent through MyChart. That feature is currently live at 150 health systems and generates roughly 1 million message drafts per month — though a staff member reviews and sends each one, rather than the AI acting alone.
Epic reports that 85% of its hospital customers are now live with its generative AI features. That is a striking number, and it reflects how quickly things have moved in the past year. MyChart Central, which gives patients a single login to use across all Epic-connected providers, is also now live in all 50 states — a meaningful step toward a more connected experience for people who see multiple specialists or have moved between states.
Athenahealth, which serves outpatient practices, launched agentic patient communication tools in February 2026. These allow patients to connect with a virtual assistant for basic questions and scheduling through text or voice, embedded directly in how practices already communicate with patients. The tools are live across athenahealth's network now, with a more capable Intelligent Patient Assistant scheduled to arrive in the second half of 2026.
MEDITECH's Expanse Patient Connect currently uses AI-driven two-way texting to reduce missed appointments and send automated care reminders in multiple languages. That is a narrower set of capabilities than Epic's, but it is live and in use at community hospitals across the country.
What's still coming — and when
Oracle Health announced its AI-powered patient portal in September 2025, and general availability is planned for 2026. The portal is built using OpenAI's technology and is designed to do something genuinely useful: explain your medical records in plain language. A patient who sees "eGFR: 52" in their lab results and has no idea what that means could ask the portal directly, and it would explain what the measurement tracks and why it matters. The portal can also help patients draft questions before a doctor's visit and suggest appointment options. Oracle has stated clearly that no personal medical data is shared with or stored by OpenAI, and the system does not generate diagnoses or treatment recommendations.
MEDITECH previewed its MyHealth Assistant at a September 2025 customer event. The chatbot is designed to help patients summarize their health information and schedule appointments using text or voice. A specific launch date has not been publicly announced.
Epic is continuing to expand Emmie's capabilities through 2026, with plans to add chronic disease management reminders and personalized health guidance. The company has more than 150 additional AI features in development for the year ahead.
For patients, the timeline for accessing any of these features depends almost entirely on which EHR system their hospital or clinic uses and what that specific institution has chosen to turn on. A patient whose hospital uses Epic will likely have access to more AI features today than one at a MEDITECH community hospital, through no action of their own.
The honest limitations
The gap between what vendors announce and what patients actually experience is worth naming directly. Industry data from late 2025 shows that while 85% of healthcare organizations have explored AI in some form, only 18% report being fully ready to deploy it in care delivery. The most commonly cited barriers are data infrastructure problems, AI tool immaturity (cited by 77% of health IT leaders), financial constraints (47%), and regulatory uncertainty (40%).
What this means in practice: a feature that is technically available at your hospital may not be turned on, or it may be partially deployed in some departments and not others. Staff training is also a limiting factor — even when tools are live, usage rates vary considerably across care teams.
The features that are live today are primarily administrative: scheduling, billing, and message drafting. Using AI to interpret lab results, flag health patterns, or offer meaningful clinical guidance is genuinely harder, and those capabilities are still being built, tested, and regulated. Patients should not expect their current health app to offer anything resembling the kind of health analysis that AI companies promote in their advertising.
There is also a calibration question about accuracy. Current AI features in patient portals are being positioned carefully to avoid clinical errors — Oracle's portal, for instance, explicitly does not generate diagnoses. That caution is appropriate, but it also limits what the tools can do for now.
Questions worth asking your doctor's office
These tools are evolving fast, and a short conversation with someone at your clinic or hospital can clarify what is actually available to you.
Step 1: Find out which EHR system your provider uses. You can usually find this by looking at what app they ask you to download. MyChart means Epic. If the portal is branded to your hospital or clinic, ask the front desk which company runs the software.
Step 2: Ask what AI features are currently turned on. Not every hospital enables every feature their vendor offers. A simple question — "Is there an AI assistant or chatbot in my patient portal?" — will tell you quickly.
Step 3: Try the scheduling or billing features first. These are the most mature and least likely to produce errors. If your portal has an AI assistant, test it with something low-stakes before using it for anything medical.
Step 4: Check your portal's privacy settings. Look for settings that control what data is shared with third-party apps or services. If you have connected outside apps to your health records, review whether those connections are still necessary.
Step 5: Ask before connecting third-party apps. HIPAA protections apply inside your EHR portal. They generally do not apply once data flows to a separate app, such as a fitness tracker or standalone AI health assistant. Before authorizing a connection, it is worth asking what the app does with your information.
Pro tip: Most patient portals have a "linked apps" or "connected devices" section in settings where you can see exactly what third-party services have access to your health data. Revoke access to any you no longer use.
What to watch for
The next 12 to 18 months will be a genuine inflection point for consumer-facing AI in health apps. Oracle's portal will become widely available, athenahealth's conversational tools will mature, and Epic will continue deepening Emmie's capabilities. None of these tools are replacing your doctor. But the administrative layer of healthcare — the scheduling, the paperwork, the decoding of confusing results — is where AI is likely to save real time and reduce real frustration. That is a meaningful improvement, even if it falls short of the more expansive vision that gets discussed in tech circles.
The question for most people right now is not whether to trust AI with their health. It is whether the specific feature their specific hospital has turned on is working well and serving their needs. Staying curious, asking questions, and starting small is still the most reliable approach.
