TESTIMONIALS

ā€œI'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.ā€ - Dr. John Lee, MD. Physician & Faculty Member, Harvard Medical School

ā€œOpenEvidence can be the foundational technology to power all clinical decision tools.ā€ - Dr. Antonio Jorge Forte, MD. Director of MayoExpert, Mayo Clinic

ā€œOpenEvidence 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.ā€ - Dr. Ram Dandillaya, MD. Clinical Chief, Department of Cardiology, Cedars-Sinai Medical Center

ā€œI am in community practice and medical director of a community cancer center. OpenEvidence has been an incredible lifeline for daily practitioners.ā€ - C.J., Oncologist

ā€œOpenEvidence is absolutely fantastic. I use it a gazillion times a day.ā€ - J.A., Neurologist

ā€œOpenEvidence’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.ā€ - Daniel Kahneman, Nobel Prize Laureate (In Memoriam)

ā€œIt is light years ahead of the next best medical oriented AI I have used.ā€ - R.E.., Oncologist

If chat GPT and uptodate had a baby. You still have to check the references obviously, but this is pretty great and accurate so far. Edit: After using for some time, still very useful, but does get things completely wrong about 15% of the time. Especially in subspecialty areas or if you ask leading questions. I learned particularly not to ask yes or no questions because it frequently gives a misleading answer.

Great tool when it works. For the last few months I've been get messages about the server being overloaded and now for the last 2 weeks the app has been completely non-functioning on my android.

Finally, an AI resource strictly for healthcare providers! Thank you!! The app functions well. It would be wonderful to have the ability for live conversations while viewing the entire text in the 'conversations' (those who use Gemini know what I mean!). I'm looking forward to seeing the future growth of this app!
