Not impressed. I've spent the past three days trying to use the latest version of Sente and have found the experience incredibly frustrating. I have 100's of pdf files already on my computer that I need to get into a good ref. database manager. The error rate for Sente not recognizing a recently published journal article is quite high. In many cases, there is a viscous loop where the program seems to be jumping to PubMed and back to Google Scholar to find the article automatically. After several minutes of waiting for something to happen (hitting the cancel button does nothing), the search ends unsuccessfully, or I have to force quit the app. A quick search on PubMed or Google Scholar directly takes me right to the reference.

When automatic importing and paper matching does work, there is a good 7-10 second lag for every paper, and this is running on a late 2009 MacPro loaded with ram. After digging into the user forums, it seems that there are serious problems with auto matching that have been unresolved for 4-6 months.

The other major deficiency on the front end of this program is that it does not support EZproxy so I cannot directly import papers from journals while working at my university computer.

Summary: I got so frustrated with trying to get things into this app. that I did not even make it to testing how well it handled scanning and making bibliographies.
