TESTIMONIALS “I've been using OpenEvidence for the last week - it has been amazing! Able to narrow down on results quickly and find information that I wasn't able to do with Google/PubMed searches on my own.” - Dr. John Lee, MD. Physician & Faculty Member, Harvard Medical School “OpenEvidence can be the foundational technology to power all clinical decision tools.” - Dr. Antonio Jorge Forte, MD. Director of MayoExpert, Mayo Clinic “OpenEvidence is more up-to-date than UpToDate. And more useful regardless, since it’s interactive, and you can ask it questions, and get very specific answers about specific medical fact patterns in a patient case. It’s like having a curbside consult with a team of expert physicians, but that you can carry around with you in your pocket.” - Dr. Ram Dandillaya, MD. Clinical Chief, Department of Cardiology, Cedars-Sinai Medical Center “I am in community practice and medical director of a community cancer center. OpenEvidence has been an incredible lifeline for daily practitioners.” - C.J., Oncologist “OpenEvidence is absolutely fantastic. I use it a gazillion times a day.” - J.A., Neurologist “OpenEvidence’s efforts to make medicine more evidence-based are invaluable. The shift from judgment to calculation can reduce the level of noise currently found in medicine.” - Daniel Kahneman, Nobel Prize Laureate (In Memoriam) “It is light years ahead of the next best medical oriented AI I have used.” - R.E.., Oncologist
