Specification revision C looks like revision B until someone finds the changed tolerance on site. Compare revisions and get a list of exactly which lines, tables and quantities moved.
Specifications, BOQs, tender documents, method statements, drawing sheets with text.
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. Tables that are identical in both documents are recognised and held out of the diff, so only cells that actually changed are reported.
The engine compares text, dimensions and notes on PDF sheets. Purely graphical changes to line work are outside its scope.
Bring two real revisions to a 20-minute call and watch the comparison run.
