Any file. DOCX. PDFs. Scans. Whatever lands in your inbox.
No converting.
No cleaning up.
No figuring out which format will work.
DOCX → DOCX
Compare docx files, and output tracked changes in a properly formatted docx you can continue editing.
PDF → PDF
Compare the documents people actually send you, and see their text cleaned up, extracted, aligned, with blacklining.
PDF → DOCX
Mixed formats can be compared too, without needing to convert files into the same formats before comparisons.
Scanned documents
Even the ugly execution copy can be handed off, as long as they are not encrypted (we can't break encryptions, by law).
Nothing generated. Nothing inferred.
There's nothing to check afterward because there's no AI slop to second-guess. Super Comparer compares the actual text from your documents. You work from the result.
