A supplier sends a revised specification. Which of the forty pages actually changed? Compare the two PDFs and get the answer as a change list and a redline, not a page-by-page reading exercise.
Engineering specifications, work instructions, manuals, supplier documents.
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.
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.
Yes. Two-column pages are read in reading order, so a column layout does not produce false differences.
Yes. The REST API accepts two PDFs and returns the change list as JSON, so a PLM or DMS workflow can trigger comparisons on release.
Bring two real revisions to a 20-minute call and watch the comparison run.
