Upload two versions of a PDF and see a page-by-page text diff, with additions and removals highlighted, plus a similarity score. This compares extracted text, not visual layout, so purely visual changes (e.g. color, font) with identical text won't show up as a difference.
The text of both PDFs is extracted and compared line by line, and the lines that were added, removed or changed are highlighted, much like "track changes" after the fact. It is the fastest way to check what changed between two versions of a contract or specification.
It compares text, not appearance, so a change of font or a moved image is not reported. Scanned PDFs have no text layer and need OCR first.
Just text — it extracts each page's text and diffs it, so layout-only or image-only changes with identical text won't be flagged.
You view the diff report directly on this page rather than downloading a file — the comparison itself is the result.
