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 a huge fan of Rayyan and regularly tell others it is the best sifting software I've come across. Quick to learn and incredibly intuitive to use, I recommend it to all new authors I work with.

I like the highlighting function, the ability for the program to predict what articles are likely to be included, the fact the program is still free, and I have received good replies when I have had problems.
