What MyChart Does Well
MyChart is one of the most widely used patient portals in the United States. Developed by Epic Systems and offered through thousands of hospitals and clinics, it gives patients access to their clinical records, appointment notes, lab results, and prescription history in one place. For many people, it was the first tool that made accessing their own health data feel possible.
Based on publicly available information, MyChart's core strengths include scheduling, messaging with providers, and viewing records generated within Epic-connected health systems. If you receive care at a major academic medical center or large hospital network, you've likely encountered it.
What MyChart Doesn't Do
The limitation that most patients notice quickly is that MyChart shows your data — but doesn't explain it. A lab result appears with a flagged "H" or "L" and a reference range, but there is no plain-language explanation of what it means, no context for whether a borderline value is concerning, and no trend analysis across multiple tests over time.
MyChart is also tied to specific health systems. Results from a different clinic, an urgent care visit, or an independent lab often cannot be added manually — so patients with care spread across multiple providers frequently find their MyChart is incomplete. Wearable data, nutrition logs, and self-reported information are also outside its scope.
For patients who want to understand their health data — not just access it — the gap between what MyChart shows and what it explains becomes a recurring frustration. This is the problem MediSphere™ was built to solve.
How MediSphere™ Fills the Gap
MediSphere™ is not a patient portal — it's a personal health AI that works with any records you upload, from any provider or lab. The key difference is what happens after you upload: the AI reads your results, explains values in plain language, flags abnormalities in context, and tracks trends across every test in your vault.
Where MyChart presents data, MediSphere™ interprets it. Where MyChart is limited to one health system's records, MediSphere™ accepts documents from any source — hospital discharge summaries, independent lab printouts, wearable exports, or specialist reports.

Privacy: A Meaningful Difference
MyChart stores your records on Epic's servers, which are subject to the health system's data sharing policies. Large health technology platforms that handle PHI are subject to their own data use policies, which may include research and commercial data sharing subject to applicable HIPAA rules — a normal consideration worth reviewing for any service you use.
MediSphere™ takes a different architectural approach: all AI processing is handled by HIPAA-compliant Private AI — no commercial AI services are used, and no health records are transmitted to commercial AI providers for analysis. Not even MediSphere staff can access your health data without your explicit permission. For patients who are particularly sensitive about health data privacy, this is a meaningful structural difference.
For more on what this kind of privacy architecture means in practice, see our guide to private AI in healthcare and our detailed HIPAA compliance overview.
Who Should Use MyChart
MyChart remains the right tool for its intended purpose: communicating with your healthcare providers, scheduling appointments, and accessing records within an Epic-connected health system. If your primary goal is messaging your doctor or viewing notes from your last visit, MyChart does that well.
Who Should Consider MediSphere™
If you want to understand your lab results, track trends over time, integrate records from multiple providers, and receive AI-powered explanations of what your health data means — MediSphere™ is built for that. It's designed for patients who are active participants in their own health, not passive recipients of data they can't interpret.

Getting Started
MediSphere™ works with records you already have — there's nothing new to generate or request. Upload a recent lab result, a discharge summary, or any health document, and the AI immediately begins interpreting and organizing your data. Your records stay private, securely processed by HIPAA-compliant Private AI, and under your control.
