DiffPDF AI - Compare two PDFs with AI and understand what changed

DiffPDF AI compares two PDF documents and shows the meaningful differences between them. Upload an old and new version to detect changed text, clauses, prices, dates, numbers, additions, and removals. AI also explains why important changes matter. Free to use with no account required.

Hey Product Hunt 👋 I built DiffPDF AI because comparing two versions of a document manually is slow and easy to get wrong. You upload the old PDF and the updated PDF, and the tool finds meaningful changes in wording, clauses, dates, prices, numbers, additions, and removals. It also explains why important differences may matter. The first version is intentionally simple: no account required, 3 free comparisons every 24 hours, and up to 20 pages per PDF. I’d really appreciate feedback on the comparison quality, usability, and what feature you’d want next.
