Compare Documents

Compare Documents takes two files and highlights what changed between them — added text and removed text, side by side. It's a diff tool for contracts, drafts, and revisions, so you can see exactly what moved without reading both versions line by line.

When to use it

Reviewing a contract redline, checking what changed between two drafts of a document, verifying that a vendor's "updated" invoice only changed what they said it did. Anytime someone sends you "version 2" and you need to know what's different.

How to use it

1. Open Compare Documents and upload the original file.
2. Upload the revised file.
3. The tool aligns the two texts and highlights additions and deletions.
4. Review the highlighted differences on screen. One comparison = one document of quota.

What the output looks like

A comparison view with removed text marked (typically struck through or red) and added text marked (typically green or underlined), in context. You see the changes inline rather than as a separate list.

Good to know

• The comparison is text-based. It works on PDFs with real text and on text-extractable files — not on scanned images. Run scans through Searchable PDF first.
• Reformatted text (same words, different line breaks) can show as changed even when nothing meaningful moved. Focus on the highlighted words, not the layout noise.
• Very different documents produce very noisy diffs. The tool shines on revisions, not on comparing unrelated files.
• Upload the older version first and the newer second — the highlighting assumes that order.
• For legal documents, the diff is a review aid, not proof. Always read the final version yourself before signing.
