Key Points

What makes it different?

PDF Search makes intelligent search. Instead of checking only existency, It analyses all pages seperately and makes a relevancy check for each of them according to given keywords. This check is similar to how a human checks documents. For example, a human is more interested on a page if it has a title containing keywords. PDF Search combines all these kind of checks into a brand new artifical intelligence algorithm. Using this, it finds the most relevant pages instantly among thousands of documents.

I had yearned for a way to search for contents in multiple PDF files, all at the same time, in the palm of my hands. I found this app, bought it, and well, without no doubt - This app just NAILS IT!

Wonderful for book copyeditors. I haven't seen another iOS app that will search multiple Word files at once and show you full results, but this app does.
