What sets it apart
A scan that already went through character recognition carries invisible text under its image. The checker sees it, so you never recognize the same pages twice.
A contract signed then rescanned, a photographed appendix: the diagnosis tells you which pages a search misses, so you only fix those.
Drop them as they are, no conversion needed first.
