Works really well!!
I’m a heavy academic researcher. I process 2,000 papers for CVPR each year, so I see a lot of PDF files. This app is great! It isn’t perfect - no app that does this can be — but it gets darn close. Figures are somehow segmented and presented separately, and it even works with two-column PDFs emitted by LaTeX! Well worth the asking price. There are some issues. In particular, papers under review tend to have line numbers on the margins of each line, which are sometimes relieved with the text in a way that’s hard to read. Still, I personally believe this domain isn’t really possible to self completely, and this app gets darn close
