A few weeks ago I came across an app in the Mac Store that seemed really awesome, but I didn't purchase it at the time and now I cannot remember what it is called. I think its primary function was a writing app. However, what struck me was that you could search for a phrase in your own writing and it would search academic databases for comparisons (this is crucial for some fields that have tricky terminology!). You could also have it search your PDF library to make comparisons with phrasings in there as well. Does anyone know what this app is called? I've been searching all morning and I cannot find it. Thanks!
