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?
I am thankful for any input. Maybe it helps someone else looking for a similar thing.
I think the collaborative part means sending PDFs from user to user and maintaining the ability to edit annotations. That may work for many use cases - a lot of businesses may be fine with that when email is still the communication medium of choice.
