DigIn has developed and launched technology to search, compare and explore multiple pdf files at once. It exceeds the industry flagship pdf products and search technologies in that all your relevant sources are in front of you on a page, paragraph and sentence level. Relevance is not arbitrary, the results are 100% accurate. We have demonstrated with overwhelming positive feedback that this deep search allows several things:- A digital archive or collection comes to life as you don't have to open and close, open and close documents, they are all "open" and under the magnifying glass of your attention;- Productivity increase. Not only is the finding of information faster, you no longer need metadata or tags;- Content in context. The technology shows you all the relations between words. Apart from the obvious, you will be able to find new relations, i.e. knowledge discovery.
