I found it a few days ago. I was using pdf xchange viewer from quite a few years and never felt the need to find something else but until now. I found this free app and tried it. I fell in love with it immediately that i uninstalled pdf xchange. This is such a cool breeze that this app does. The only gripe i have is, it doesn't generate pdf thumbnails in explorer which pdf xchange did. Other than that it is a great app.
This app offers a seamless user experience with intuitive features that make tasks effortless.
It covers all I need, it is authentic, equipped with a good AI bot and moreover it is really and 100% free and ads free at the time. The only draw back might be it is not cloud based or abale to sync between devices, which still is not a deal breaker for me. Considering all the feature that it gives me, I adapt myself with it instead of complaining nonesence. I am against subscription model of businesses for tools that are nowadays are part of basid human rights like PDF editor, word processing. etc. Such tools and services are so integrated in human's life that having unconditional access to them are like basic rights such as free education and freedom of speech. I am not sure how I can help or support their team, but if there is a one-time purchase, or support requests, I would voluntarilypay.
