I have prosopagnosia (face blindness) and apparently the descriptions of the people whose voices you can choose from aren't even accurate (e.g., it listed "VP" under an image of the democratic nominee who lost the 2016 presidential election ಠ_ಠ). There's also no search option and it seems to focus ... Show more on famous people like political figures, live action actors, and few, if any, voice actors. Also, there's an ad stuck at the top of the screen promoting their "pro" version, which they claim has AI that will users to make money.
Overall, very annoying user experience. Too focused on making money and/or avoiding potential legal issues.
