Why Xebra™ Pro is Unique:

• CLINICIAN-MIMICKING DDx: Instantly arrive at a high-confidence differential diagnosis of an *unlimited number* of symptoms and all their qualifiers, and any number or combination of physical signs and lab results. But of course you won’t want to just believe us – try it yourself!

• SMART WORKUP: Instantly get a comprehensive workup strategy that gives you a serious plan for what to do next:
o what other symptoms (and qualifiers) to ask about
o what physical exams to conduct
o what labs and tests are most appropriate and useful to order (and, by what Xebra leaves out, which are likely not)

• WORLDWIDE EXPERT CROWD-SOURCING: Provide feedback (“Contributions”) on any suboptimal answers you ever find. We will quickly integrate them into the algorithm to make your expertise available to every clinician everywhere, for all time! That will ensure the same suboptimal result never happens again on the same inputs, to anyone. And you’ll get credit!


Our mission is to empower clinicians and their patients and caregivers, and to reduce waste and avoidable human suffering. We’re well on our way to fulfilling that mission, but it can get even bigger, with your help.
