A revised maintenance procedure has to be read against the previous one, and every changed step matters. Compare the two revisions and get a list of exactly which steps, limits and warnings changed.
Maintenance manuals, operations manuals, procedures, airworthiness 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. Every change carries the page it appears on in both the old and the new document.
Yes. Repeating headers, footers and page numbers are recognised and excluded, so a changed revision date in the footer is reported once, not on every page.
Bring two real revisions to a 20-minute call and watch the comparison run.
