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.
