I didn't know it was going to cost money. I am just a private person trying to get Medicare reimbursement. The print is very tiny so proofreading is hard.

This is only used once in awhile. Being able to take a PDF and change it to Word document. Being able to add comments to a PDF is easy as well. This needs easier user instructions so use can make the changes needed. It can difficult to find the processes.
