Procurement

PDF comparison for procurement teams

A corrigendum re-issues the whole tender document. Compare it against the original and see the changed eligibility criteria, dates and technical requirements without re-reading two hundred pages.

What procurement teams compare

Tenders, RFQs, corrigenda, bid documents, purchase contracts.

What you get

How the comparison works

Text is extracted from both PDFs with its position and style. Repeating headers, footers and page numbers are removed, unchanged tables are recognised and held out, and paragraphs are aligned across the two documents before a character-level comparison. The output is a change list with page numbers, a redlined PDF and a side-by-side view with synced scrolling. The engine is deterministic: the same two documents always produce the same result.

Deployment options

Use the web tool for individual reviews, the REST API to trigger comparisons from your document system, or a private deployment in your own VPC or on-premises when documents cannot leave your network.

Questions from procurement teams

How long does a 200-page comparison take?

Typically under a minute on the API tier. The web tool is sized for documents up to 100 pages.

Can the change list be exported?

Yes. The API returns changes as JSON with page numbers, old text and new text.
