I mean, it's cool and all, but the idea of giving someone I know nothing about doesn't sound that appealing :(

Of course, I could make a separate throwaway email, but then the main benefit if this service (convenience) disappears.

Lack of a clear monetization model makes my inner paranoid even more concerned: looks too much like an attempt to collect emails for some nefarious purpose. Why else would you allow literally anyone to just burn your money? OpenAI API is not that cheap.

Sorry, maybe I'm just not in the target audience.
