I’ve tried a lot of PDF annotation tools, and this one is by far the most pleasant to use. It just works. Everything is logically laid out, and it’s incredibly easy to navigate. The design is clean and modern, making the whole process of reviewing documents much less stressful and surprisingly enjoyable. I highly recommend it!

As a Project and Quality Manager, I spend a lot of time reviewing documents. This was always clunky and frustrating. Theoros has completely changed that for me. The interface is beautifully designed and incredibly intuitive. I can quickly find what I need, add my comments, and move on without any unnecessary steps. I genuinely enjoy using it now! If you’re looking for a PDF tool that’s both powerful and a pleasure to use, look no further.
