CiteStack is an extension to Google’s Chrome browser. In order to run CiteStack, you must first install Chrome. When you do legal research using Google’s Scholar site, CiteStack interacts with Scholar to save your results.
For example, if you highlight a selection in a case, CiteStack automatically captures the selection and generates a pincite for you. You determine whether and where to add the selection and its pincite, and you can save an annotation as well. Nothing is saved unless you chose to add it to the Stack.
You can try it for free; but a one-year license is $69.00.
