Questions people ask
Does this compare visual layout or just text?
Just text — it extracts each PDF's text and runs a line-by-line comparison. Visual/layout differences aren't detected.
Does it need an internet connection or AI?
No — this is a straightforward text diff, computed entirely in your browser, no AI involved.
Are my files uploaded anywhere?
No — comparison happens entirely in your browser.
