eing a new user of this platform I had a major issue and they went over and beyond to fix it and made it up to me even tho it was my fault for not reading. ha

Honestly- it is not straigth forward tool- you need to spend time and learn how to use it so it is not exceptionally user friendly.
I found SignNow very complex!

What do you like best?
I like that you can save the template for a certificate of insurance or an application and send it out that way. It still saves it as new but also creates the new Document.
What do you dislike?
The same feature that I love so much, isn’t quite as easy to navigate on the App. It’s super easy on the full online version though.
What problems are you solving with the product? What benefits have you realized?
Super easy to use on the go with the App access. I live that part of it.

Learning how to use pdffiller
I'm just learning how to use pdffiller, and it's very easy to pick up. Of course, I've had to ask their tech support for help, and later discovered the answers were simple and in my face! It's all there. Tech support is great. They get back to you asap with very friendly and pertinent info.
I especially like the fact that you can create paperless docs and set them up to reuse them as templates. I think it's a great product!

First, the website works really well - lots of options to accomplish any task, pretty easy navigation, and reasonable pricing (one-time use is even free!). **************** is outstanding.

Pdffiller- I used this site to help me with a paper. I had signed up for a free trial. Thought I had canceled subscription. I found I had a charge from them today and immediately contacted them. Without hesitation they refunded my money with quick and timely friendliness. ****** thank you for your help!

I have tried various programs to change PDF's, and I find this one the easiest to use. It is much more intuitive than some of the others.

It's pretty nice for a PDF-filling application. Wish I could do a reasonable one-time purchase instead of having to pay monthly, though.

How does text classification work?
It exclusively compares the input text with the training texts included in the model. In other words, when you train a model you associate each category to sample texts, so that when you enter a text to classify, the system will compare it with the examples and will determine which one is the nearest.
