I am using this tool for my research work as it helps me with organizing all relevant information about different articles that are published online or offline by providing links which makes searching easy through keywords search option of datazar itself! It's free so there isn't much downside however you can pay if needed also but still its totally worth giving try out once before deciding whether your willing spend money over something like these things? The best part being no need to download any software/applications etc., just few clicks & everything gets organized!!
