Con Notevibes is the better option on Mac and Windows
Natural Reader can be used for a wide range of video and instructional design products over the years, but a more cost-efficient app that is very similar, is cloud-based, and it is only $9/month (and you can cancel it at any time). It's called Notevibes, and you can check it out at:Notevibes.com
Con Free version available, but upgrades are costly
$69.50, $129.50, or $199.50, does not appear to be a lifetime purchase, there seems to be a limit on how many images that can be used with the OCR function within the different tiers.
Con Few hotkeys, not user configurable
The shortcuts/hotkeys that exist are simple and work well, but they are not user configurable which might be a problem for some. The app is more GUI driven, a travesty since accessibility is a big attraction for people seeking software like this.
Con Unstable on MacOS High Sierra
Encountered stability issues on MacOS High Sierra. Changing voices or opening a .docx Word document can cause crashes.
