Frequently asked questions

How many files are needed?
Exactly two — for example, two revisions of the same contract.
What does the report show?
Per-page highlights of the differences: what changed, what was added, what was removed.
Can scans be compared?
Text-based PDFs compare best; for scans it helps to run OCR first.
