    ZetaMarker is the best highlighting tool I've used. It has a clean, intuitive interface that makes highlighting and organizing information incredibly easy. One of my favorite features is the ability to upload and work directly with my PDF files, which makes studying and reviewing documents much more efficient. Overall, it's a fantastic tool with a great user experience. Highly recommended!
