Zebra Scout

When doctors hear hoofbeats, they think horses.
Sometimes it's a zebra.

⚠️ This is NOT a diagnosis

Zebra Scout helps you identify possible rare conditions that match your symptoms β€” so you can have a better conversation with your doctor. It cannot and does not replace professional medical evaluation.

How it works:

  1. Enter symptoms β€” search from medical terminology or describe in your own words
  2. Get matches β€” see which rare conditions share those symptoms, ranked by overlap
  3. Talk to your doctor β€” bring the list to your next appointment as a starting point

Why β€œZebra”? In medical school, students are taught: β€œWhen you hear hoofbeats, think horses, not zebras.” But for the millions of people with rare diseases, the answer is the zebra β€” and it often takes years and dozens of doctors to find it.
