All right, these are my impressions of Recogito Studio after the software demo:
The software seems very mature. For users, there are:
the possibility to reply to comments
Comments can be private, read-only or only visible to certain groups
You can create reading assignments and link them to documents
Not only texts, but also images can be annotated
annotations can be exported as CSV (PDF export is in the making)
annotations can contain rich media (e.g. embedded youtube videos or images)
For admins:
can define different roles (instructors, students)
Login is possible via SAML
The software is GDPR-compliant
in this short video, you can see how the software works:

I pointed the team to this very thread, maybe someone of the developers might join this discussion. Again, I'd be very glad if we had Recogito Studio available on Cloudron.
