Oh, well, it's plugable, just GOCR is all I have :)

In general, it does a bunch of cleanup to make the OCR reasonable.  I
wouldn't say it's anywhere near perfect, but it seems to pull most of
the keywords out of things like credit card statements.  I would say
it's good enough for search, but it's not perfect by any stretch of the
imagination.

+1, I wouldn't use it for archival things like that yet.  But, you might
be able to use GOCR with the work Google is doing -- I'm not sure if
they're open sourcing all of it or not.
