#2Is this based on an open-source OCR engine, a proprietary engine running on your own server(s), or a proprietary engine you're accessing as a service?
Re: Show HN: Convert scanned documents into searchable PDFs
#3I would use this service, if I had scanned PDFs where I didn't care about confidentiality. As it stands, though, uploading them to an unknown web resource seems risky.
Thoughts?

#4While interesting, and looks to be a needed services, the page leaves many questions, such as:
What's the privacy model? While the PDFs are deleted, what happens to the searchable content? Is it also deleted?
What's the revenue model? How can we be sure it'll be around in a few months?
Is there an AJAX interface?
Is the quality or performance better than running Tesseract on a server?

Given that the OCR'ed PDFs use the "GlyphLessFont" font, it seems that tesseract [1] is used.

#6Very clean UI. But how can one judge the OCR quality of this service? The service presents me a converted PDF, but how good was the conversion?
Is this better than https://ocr.space ?
For my private documents I would always use offline OCR software like http://blog.a9t9.com/p/free-ocr-software.html

#7I just use the OCR function built in to Adobe Acrobat.
Don't know it the OCR function is available in the reader version.

I hope not. Tesseract delivers bad results on high quality scans, far below the same OCR quality achieved by services like Google Books.
What the OCR market needs is someone who will bring that level of OCR quality - or better - to the masses (perhaps some deep learning grad student with time to kill?), not yet another wrapper around Tesseract. We have those already!

I have had great result using tesseract via gimagereader. Are you sure your configuration is good?
