"Is this the same version they sent last week, or did a clause change?" — one of the riskiest questions in contracts. Comparing two PDFs by hand is tedious and dangerous: a single changed date or amount can slip by. AI brings this down to seconds.
The risk of manual comparison
Reading two long documents side by side demands focus; across pages of text it's easy to miss an added sentence, a removed exception or a changed figure. And formatting differences (renumbered clauses, shifted paragraphs) can hide the real content changes.
Comparing with AI — step by step
- Upload both versions: Add documents A (old) and B (new) to the Compare PDF tool.
- Compare: The AI understands the text and extracts added, removed and changed clauses.
- Review the differences: See binding changes in particular: amounts, dates, terms, parties, obligations and penalty clauses.

When is it most useful?
- Checking contract revisions before you approve them.
- Seeing what changed in tender/spec updates.
- Understanding what the other side's 'minor edits' actually contain.
If you want to understand not just the difference but the whole document before signing, the Summarize and Chat with PDF tools let you ask questions about it.
