Don’t get me wrong, I love writing and editing text on the computer, but even I sometimes wish that annotation on the computer was like annotation on real paper. Almost every word processor has some sort of annotation functionality built right in, and while these solutions are effective, there’s just something about using a pen or highlighter to make notes on paper. When I wrote my screenplay, I loved taking time to flip through the pages and write notes on areas that needed to be reworked, but I don’t get the same enjoyment out of annotating digital documents. Bookgoo doesn’t replace your pen and paper, but it sure comes close.

Once you’ve uploaded the document that you want to annotate, you can then draw and make notes on it just like you would with a document that you hold in your hands. As you’d expect, collaboration is a big part of Bookgoo, and you can easily see the contributions that each participant has made to the document. This is the way that documents should be annotated online.
