Isabel Healthcare uses the symptoms you enter to
suggest a list of medical diagnosis possibilities. While it does not provide medical advice, from the list
you can read a Wikipedia article on each topic to narrow it down. For a limited
time a version is free to individuals with no account needed. It covers about
6000 conditions.
Isabel was designed by a dad with the intensive care
doctors who treated his daughter Isabel during a health crisis. The system can
help consumers “make sense of the vast
amounts of medical knowledge out there, become better informed and work
constructively with your doctor to find the right diagnosis as soon as
possible.”
Although no account
setup is required, a help manual is linked on the registration page.
