Frequently asked questions
What kind of changes does it detect?
Text that was added, removed or altered between the two versions, shown in place so you can see the surrounding context.
Does it work on scanned PDFs?
Scans hold pictures of text rather than text. Run OCR on them first and the comparison will then have text to work with.
