I started using Paperpile and I like it for its simplicity. Currently, I use a chrome extension called “PowerNotes” to manage my literature review as it is a handy extension that helps me annotate and save notes. The best part of PowerNOtes is that you can organize your research and then convert it into excel or word doc.
This is very helpful as the researcher gets a better understanding of a Literature Review Matrix in excel. The current annotation feature with Paperpile is good but exporting annotations and notes are limited to formats like HTML, PDF, etc. Can you please add Doc and Sheets as an export format? It will be a big help.
