I've used a number of highlighting tools over the years including Weava (too buggy), Liner (too intrusive and expensive), and many other chrome extensions that never came close to nailing it. I'm thrilled to have finally found ZetaMarker. It highlights my local PDFs perfectly and remembers where I left off, retrieving documents from my local drive to continue my highlighting. Customer service is top notch. Kudos!
A great tool, specially for reading and editing pdf files. I really enjoy using it, I wish it was also available for corporate usage, as my employer blocks add-ons.
I like this tool because it makes online search, reading and highlighting important parts easy and saves time.
Using the tool is intuitive. Great for research. Love it!
A great tool! The unique problem is: It should have an option to make zetamarker always enabled. It is always disabled until I enable it. That is not great as I usually forget whether the current page contains highlight or not....
It's really helpful tool for me to do my research. It makes my research easier and saves my time.
Very useful and user friendly.
As a researcher, I was seeking a platform through which I could highlight what I read online. I had many problems with pumps of downloaded pdf papers that I needed to highlight. ZetaMarker solved my problems. Altough this is a short time I know ZetaMaker, I could make the most out of it in my research. It is a clever idea.
ZetaMarker is a great and user-friendly tool to help you saving your time while reading online or researching.
ZetaMarker truly elevates online productivity and empowers users to take control of their research. Whether you're a student, researcher, or professional, this extension is a must-have. Its powerful annotation tools, seamless integration, and the promise of upcoming smart features make it an indispensable companion for anyone looking to enhance their online research capabilities. Give ZetaMarker a try, and prepare to unlock a whole new level of productivity!
