“ 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. „

“ This is a great tool. We whizzed through 250+ hits in a couple of hours. It is a great feeling to work online and feel the burn. Some people like to jog on their own.... Rayyan is a bit like a jogging trainer! Good job. „
