I used it in a few projects. Covidence is a platform that helps us to do T&A screening, Full-text screening, and more...It can also remove duplicates as well. However, I used it up to the screening, and very useful when we do screening independently...

@Veettil thanks for your response, am also planning to use it for a screening of thousands of records together with my team

Covidence is simple to use, and makes the process of duplicate screening easy (showing the conflicts). It isn't the fastest to use for the first cull, as it shows you both the title and abstract at the same time, and for some topics, it's more efficient to go through just the titles first. So for larger systematic reviews where you have a lot of irrelevant titles to go through, I prefer Rayyan instead.
