Comprehensive, efficient and intuitive functionality. The only capability I missed was use of the arrow / scroll keys. A simplistic and refreshing technical experience. Thank you!

I love this app I love this app, it makes sure to compensate for all the things which you would need to do for schoolwork. Personally though, I think it would make more sense to market it with ads rather than subscription. This is really useful for students who are homeschooled or aren't able to go to school and students usually don't have much in their pockets to pay for these kinds of things.

Easy to use! I found the system very easy to use and have only scratched the surface. Converting documents to an editable form was easy to do and the system made it easy to find available PDF or other formatted versions online. Saving different versions or templates was a bit of a challenge but that was easily remedied.

Time saver! I have used PDFfiller for several months now and love it. It is a great tool which makes it extremely easy for me to quickly and efficiently fill out PDFs and return them to the sender. Wether it be filling out forms or signing a contract, it has saved me many many hours in the long run - and is a pleasure to use! There aren't really any cons to this plugin - it does exactly what it says it will do. However the user interface could be improved

A proper company PDFfiller apparently thought I wanted a subscription to their service after trying it out once. I did not want that, however, and wrote to them to cancel the payment. They cancelled right away, no questions asked. You know a proper company when that is the procedure.

What do you like best? The ability to modify documents specific to our needs. The Tools provided give me maximum ability to modify, add, remove and edit any document in any way that is needed. What do you dislike? I haven't encountered anything I dislike about this product. What problems are you solving with the product? What benefits have you realized? It's helping us to create documents that are needed specific to our clients rather than generating generic and boilerplate documents that are not personalized to our clients.
