What people are saying

It’s totally ace and I’m pleased to see this development where you can do screening in duplicate. It’s so intuitive you don’t really need the user guide. I’ve done several reviews and one of the worst parts is matching the inclusion/exclusion decisions between review authors to decide what references to retrieve – this couldn’t be easier thanks to Rayyan.

I am building a database called ‘Oral Cancer Organization: Evidence Based Resource’. Rayyan is really helpful, I am very interested in it and believe it can be used for automation of daily/weekly/monthly updating the database. It's the best, Rayyan is the back-bone of the whole project. We would not have dared to think about doing something like this.
