I love it when I can pickup an LTD tool that allows me to cancel a subscription. I've been using Adobe Acrobat for years, and even though it's just $20/month, my needs are to view PDFs, organize them, maybe once in a while edit, and then signatures - relatively basic. uPDF allows me to do all of that (and probably more). I'm not sure about the add-on (not part of the deal) for uPDF AI (I wasn't using any AI add on from Adobe, either), so not sure how that enhances the tool for anyone. If your PDF needs are relatively basic, pick this up and cancel your Adobe subscription. Great purchase.
