This one needs an upload, and is deleted afterwards
Browsers cannot do this calculation, so the file goes to our server. It is deleted automatically 60 minutes after the job finishes, and the working copy lives in a memory filesystem that is wiped whenever the server restarts.
We do not log file names and do not log file contents — that is a hard rule in our engineering standards, not a setting.
What it does — and what it doesn't
Layout spacing between CJK characters is ignored, while spaces between Latin words are kept — otherwise the entire document would register as different.
It compares text, not appearance. The same words in a different font or position are not a difference.
Scans cannot be compared — no text layer, nothing to compare. Run OCR first.
Changes to images, table rules and signature stamps are not detected.
Common questions
Will it tell me a paragraph moved?
It will show a deletion earlier and an addition later. Line-by-line comparison cannot infer intent.
Can the two files have different page counts?
Yes. The extra pages are marked as additions.
Is it good enough for contracts?
Good enough to tell you which lines to read. Not good enough to be the only check — a person should still read anything that matters.
