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'm not aware of anything else which does the same or a better job.

Nice tool -- in addition to facilitating article screening (inclusion/exclusion), seems to have the ability to facilitate topic development, e.g., by helping map out preliminary evidence with the keyword highlighting and sorting on the left hand panel.
