## OpenEvidence Reviews in United States

### ***** "Excellent and accurate resource"
I have been using this app for quick searches during clinic, and it has proven to be an invaluable resource. The information provided is consistently accurate, with concise and reliable references. It has become an essential tool for my day-to-day practice.
-- myasirqureshi, 2025-01-02

### ***** "Unbelievable"
This was a seemingly random email that I received, but it’s been an absolute game changer. As a physician, it’s incredibly valuable to be able to run an evidence based search of the literature and not have to sort through the Google quagmire. I’m currently putting together a grand rounds talk. I have an instantaneous answer to my questions with citations that saves me hours of pubmed searches. Machine learning will change the way that we practice and this is a step in that direction.

Excellent application

Just a measly resident physician and the ability for this LLM to find and accurately put together up to date literature is so, so impressive

If you take care of patients, this resource will make your life easier. There’s no reason not to lean in and spend less time looking for answers in nuanced clinical practice.
-- LombardDO, 2024-12-11

### ****- "Great new resource"
I have been using the app for about 2 months and have been very happy. It does have some difficulty with complex questions though a very low hallucination rate by comparison to many other bots.
-- Drewski011, 2024-12-04

### ***** "when User uses it properly"
really beneficial quick search for that searing question honestly. sometimes requires very good specific precising in order to get the desired answer instead of an aberage answer. but if u use it right, its incredible. 10/10
-- anicknameidk216, 2024-12-01

### ***** "Dr."
Amazing medical information
-- Dr Yeny, 2024-11-27
