I hope I'm not overstepping my bounds by I am just really trying to understand this product better because it is trying to address a core deficiency of AI, however what you have presented I don't see how it solves the problem.

You essentially admitted that instead of $0.05 a request, you could just regex and replace.

In fact the regex and replace would be 100% accurate at never giving up the secret phrase. where your product is incredibly expensive and doesn't do what you advertised (unless i am misunderstanding when you said that someone won the game by getting the phrase you were trying to protect)

How is this product useful in any meaningful context?
