I was hesitant to even try because it demanded a login. Then, I saw usage limits and upgrade for $ and immediately removed it. The single test I did wouldn't even copy (to the clipboard) all of the text that it managed to recognize; only a small rectangle.
Costs money (quote from author: you can now use it 15 times per day for free, and to get 100 uses per day you need to upgrade.), requires Google login, but most importantly, it doesn't even properly copy small, but easily readable text.
