Comments about Qiqqa as an Alternative to Mendeley
Differently from Qiqqa, Mendeley has no annotation report feature, meaning that it is not possible to gather all highlights/annotations on a paper into a single file. This is very useful for large pdf.


- Qiqqa is Freemium and Open Source














Has the feature to tag regions of a pdf with a keyword or add a note with a tag and later compile all occurrences of the tagged regions with a particular keyword across the whole library..
