FreeMD.com is website which conducts a short interview starting with the main symptom and assembles a list of likely diagnoses. The questions and answers are done via short pre-recorded videos by a real physician.
Try some allergy-related queries like "rash", "runny nose", "wheezing" to see how it works.
The website can also be used for education of medical students and residents -- it guides you through the high-yield questions and the most likely causes of symptoms.
In my tests, the online diagnostic tool FreeMD worked well, and due to its large number of pre-recorded videos, it was interactive and fun to use. Dr. Val and Happy Hospitalist also tried the website with a few different scenarios but they did not think it was ready for clinical use:
