Are you struggling to annotate textbooks and articles digitally?
If you’ve been shopping around for PDF annotation software, you might have run into these problems:
- In some free PDF readers, the highlighter colors are too dark and it’s hard to read the text underneath
- Some browser extensions are great for highlighting text on websites but don’t work as well for highlighting PDFs
- Free PDF readers—and even some paid options—lack optical character recognition (OCR) technology, which makes annotating scans and images impossible
- Not all PDF editors allow you to sync changes across your devices; not all integrate with iOS’ Files App
If so, know that there is PDF annotation software that meets all your annotation needs and that syncs across your Mac, iPad, and iPhone, freeing you to annotate from anywhere.
