Makes a few errors
This app seems to struggle somewhat with uppercase English text. When extracting text from a TIFF I noticed it tends to misread D or Q as "O", and VV as "W" or even "WV". Very occasionally gives "L" in place of I. If accuracy is important for your project be sure to give it a good proofreading before proceeding. Still, it's frequently able to find text where Adobe Acrobat would fall flat on its face, so 3 stars for that.
