I was looking for a PDF editor that could address my needs without breaking the bank. The aim was to have a PDF solution that could offer an alternative to Adobe and still be easy to use, be simple in the integration and do all the things that you would expect from a PDF editor such as highlighting, editing, converting and of course creating of PDFs.The ability to combine it with an AI tool is also interesting and even though you have to pay extra for the AI integration it is well worth it. I have been able to save a love of time either summarising long PDFs, extracting key elements, ask questions and generally help to speed up dealing with big documents.I use UPDF on a regular basis, especially when looking at client work to allow me to quickly scan through documents, allowing me to focus on essential parts.
