Real Questions, Real Answers
This is what Caedrix AI is actually for.

Three real situations. See what Caedrix AI tells you — then try it with your own.

Health Decision
"My grandmother, 83, was just diagnosed with uterine cancer. Should she have chemotherapy?"
Caedrix AI's Response (illustrative)
·At 83, the chemotherapy decision depends less on age alone and more on her overall health, the cancer's stage and subtype, and her personal goals — comfort and quality of life vs. maximizing time.
·For early-stage, low-grade uterine cancer, surgery alone may be curative and chemo may add limited benefit relative to its toxicity in an older adult.
·For higher-stage or aggressive subtypes, chemotherapy can meaningfully improve outcomes — but tolerance, kidney/liver function, and existing conditions matter as much as the cancer itself.
·Questions worth asking her oncologist: What stage and subtype is this? What does chemo add on top of surgery/radiation? What would a geriatric oncology assessment show about her fitness for treatment?

Understand a Diagnosis
"My friend was just diagnosed with polycystic kidney disease. What does that actually mean?"
Caedrix AI's Response (illustrative)
·Polycystic kidney disease (PKD) is a genetic condition where fluid-filled cysts gradually replace healthy kidney tissue, most often inherited from a parent (autosomal dominant PKD).
·It typically progresses slowly over decades — many people function normally for years before kidney function declines.
·The main things to monitor are blood pressure, kidney function (via bloodwork), and cyst growth — high blood pressure is both a symptom and an accelerant, so controlling it matters a lot.
·Newer medications can slow cyst growth in some patients, and family members may want genetic counseling, since it's hereditary.
·Caedrix AI also surfaces recent research and actively enrolling clinical trials relevant to her specific case — for PKD, this could mean trials testing newer cyst-growth inhibitors or kidney-protective therapies she may qualify for.

Determine a Diagnosis
"I'm 35 and healthy, but I have blurry vision and keep stumbling. No one can tell me why."
Caedrix AI's Response (illustrative)
·Blurry vision plus balance problems in a young, otherwise healthy adult points toward a handful of possibilities worth ruling in or out — most commonly a vestibular (inner ear) issue, a neurological cause such as multiple sclerosis, or a metabolic cause like a B12 deficiency or blood sugar issue.
·The pattern and timing matter: Are symptoms constant or come in episodes? Did they start suddenly or build gradually? That distinction changes which cause is most likely.
·A reasonable next step is a neurology referral for an MRI and neurological exam, plus baseline bloodwork (B12, blood sugar, thyroid) — both are relatively quick to rule in or out.
·This combination of symptoms is not something to sit on — it's worth pursuing an evaluation soon rather than waiting to see if it resolves.

Why I Built Caedrix AI

A physician who became
the patient.

One Saturday morning, I woke up and my heart was racing. I'm an orthopedic surgeon with 35 years of experience. I knew what atrial fibrillation was — I just never expected to be the one with it.

I couldn't get into urgent care. I was second-guessing myself about whether I really needed the emergency room. So I turned to AI and asked.

"Go to the emergency room now. Do not wait."

— Claude AI, that Saturday morning

It was right. I was in AFib. Over the weeks that followed, I used AI to analyze my own CPAP data, research four complex treatment options, and walk into every specialist appointment prepared — asking sharper questions and understanding the trade-offs in ways I couldn't have without it.

My doctors made every decision. But AI made me a better patient. And I realized: I'm a physician. I had advantages most people don't have. What about everyone else facing a diagnosis alone?

This platform — Caedrix AI — is my answer to that question. Not a replacement for your doctor — I believe deeply in that relationship. A health coach that helps you show up prepared, understand your own data, and advocate for yourself when the stakes are high.
