what our users say
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!
