Docear is a unique solution to academic literature management, which helps you organizing, creating, and discovering academic literature. The 3 most distinct features are:
A single-section user-interface that allows the most comprehensive organization of your literature. With Docear, you can sort documents into categories; you can sort annotations (comments, bookmarks, and highlighted text from PDFs) into categories; you can sort annotations within PDFs; and you can view multiple annotations of multiple documents, in multiple categories – at once.
A ‘literature suite concept‘ that combines several tools in a single application (pdf management, reference management, mind mapping, …). This allows you to draft your own papers, assignments, thesis, etc. directly in Docear and copy annotations and references from your collection directly into your draft.
A recommender system that helps you to discover new literature: Docear recommends papers which are free, in full-text, instantly to download, and tailored to your information needs.
Last, but not least, Docear is free, open source, available for Windows, Linux, and Mac OS X, and not evil. In addition, it can be used stand-alone or together with reference managers such as Zotero or Mendeley
