great except when i want to email something sometimes the other party can't view it as a pdf. i dont get why. I want an option to save my new document in my own hard drive but can't figure out how to other than emailing it to myself. add that option or help me find it.

PDFfiller saved me. I had forms to fill out for my college class and I could not get my computer to work. I could not edit them! Using PDF filler helped me get them all done. Thank you!

It's very easy to edit the documents… It's very easy to edit the documents and a lot of flexibility was put into thought in pdffiller and I'm very impressed.

An Affordable and Easy Solution for Businesses Handling E-Signatures As an inexpensive and simple tool for signing documents digitally, pdfFiller is unrivaled in value compared to other solutions offered by Adobe and others. Our company uses pdfFiller constantly to compose property deeds for our owners. We also prepare a variety of documents for our Board of Directors to sign conveniently since they are not onsite always. It does cost more money in monthly subscription fees to have faster access to customer service. At the first time we experienced a technical problem and needed a question answered we did not have the service tier that afforded same-day replies from customer support. This was an inconvenience, but we have since upgraded our services.

Quick on the go use This software allows for quick on the go use with only my cellphone. No need to print, fill out, scan and email. There are several applications I have not used with this software

Making signing easy It was a great team friendly program that made things get done a lot faster and more efficiently even in large with large numbers working on the same thing. Makes getting multiple groups of people working on one thing done faster with not all having to come to the same place. Sometimes it was difficult trying to download the papers once the words were added.

Easy to use Easy to useAllows the user to do things like make forms fillable very quickly. The size of the fields I added were slightly bigger than I would like, but this was not a major problem. Otherwise, I think it's intuitive and pretty easy. My needs are fairly simple, though - just making a workbook fill-able by students working online.

Open the documents that you want to compare. On the Review tab, in the Compare group, click Compare. Click Compare two versions of a document (legal black line). Under Original document, browse for the document that you want to use as the original document.
Open one of the two versions of the document that you want to compare. On the Tools menu, point to Track Changes, and then click Compare Documents. On the Original document pop-up menu, select the original document.
The most common way is to measure the similarity between two text documents is distance in a vector space. A vector space model can be created by using word count, tide, word embeddings, or document embeddings. Distance is most often measured by cosine similarity.
One way to find semantic similarity between two documents, without considering word order, but does better than tide like schemes is doc2vec. Doc2vec converts each document into a vector, and semantic similarity can be computed by cosine distance as you mentioned.
Cosine similarity measures the similarity between two vectors of an inner product space. It is measured by the cosine of the angle between two vectors and determines whether two vectors are pointing in roughly the same direction. It is often used to measure document similarity in text analysis.
Unmerge is an Open Source difference and merging tool for Windows. Win merge is software that allows you to compare two text files side by side. It will automatically scan a document for any differences and will highlight any of those differences.
