About this tool
Find every change between two versions of a contract, quote or price list. Text mode highlights words that were added or removed on each page. Visual mode overlays the pages and highlights pixel differences, which also catches changes to images, logos and layout.
Frequently asked questions
Does it work on scanned PDFs?
Visual mode works on scans. Text mode needs real text, so run OCR on scans first.
Are my documents uploaded?
