Human-Visible but Camera-Resistant Text

Hi,

I would like to have option like text which is visible to us i.e human eye but not visible on camera from side view or slightly far from pc In order to cheat in double camera test such as Duolingo which have double cameras the one is front camera from pc and the other is secondary camera which is placed that the entire screen and keyboard is visible. So this is the feature I want in parakeet ai.

Regards,

Ahmad
