The returned-document ritual
A contract comes back "with minor changes". The honest options are re-reading forty pages or comparing — and comparison shows each difference in seconds, including the ones "minor changes" undersold.
Text-based files compare best
Comparison diffs the text, so digital PDFs compare precisely. Scanned versions need free OCR first to have text at all — and OCR noise can create phantom diffs, so verify surprising differences on the page. Files are processed temporarily and deleted automatically — there is no general cloud storage.
