works great

Works great as advertised. OCR (English) on my scans are pretty consistent (just some misses). Have not tried other languages. The deskew feature is very useful (some pages remain skewed though). Deskewing landscape pages gives weird results. However in-app ability to rotate landscape pages before deskewing & then OCR-ing is also handy to avoid this issue & let me OCR all pages. Have not had occasion to try integration with scanner as I have other means and only intend to have this app OCR existing PDFs. Have not an occasion to try “fake duplex” either as Apple’s own utilities have that ability though doing it in-app has got to be more straight forward. I’m slightly puzzled by the claim of small file sizes however. The 4 files I tried started out from 4.1MB to 8.8MB (62 to 124 pages at 150dpi b&w) and after deskew & OCR became 31MB to 61MB. To get to 5 stars, my suggestion is to enable Asian character OCR as well.
