Does not work
I don’t often need OCR, so I gave this free version a try. Unfortunately, it simply does not work. My source was a very clearly scanned single page PDF image of a table with names and ages. Converting it to txt resulted in garbage, with not a single word from the file recognisable. The searchable PDF I tried next was also not searchable. Bottom line - stay away from this one.
