I am looking for a solution to collaborative PDF editing (mostly annotations). I already have a Nextcloud installation with Office for several members so it would be great if it could be integrated, but it is not necessary.
What I mainly want is the possibility to add and view annotations made by several users on the same file at the same time.
Do you have a suggestion?


That’s not an option unfortunately. The actual use case is a non-profit sports club magazine which needs to be proof read by several people at the same time. There is a fixed release date and only a few days to proof read the PDF before it needs to be sent to print.
