Interactive complements

Hello everyone. We are recquired in order to be part of an indexing system, we need to add some interactive functions with the readers, such us comments or an alert system. I can’t find any complement with that kind of features, but maybe I’m not searching properly. The question is if this is possible and how can I figure it out.
Thank you very much, and sorry if the message is confusing, English is not my first language.

Regards,
Ana.

Hi @Ana_Clara_Caccia,

Have a look at the Hypothes.is plugin; it’s available in the Plugin Gallery.
