people in this thread are literally feeding a cipher into chatgpt, as if they're ignorant of the fact that chatgpt is fundamentally weak at doing letter substitution and transposition and shit due to being an engine based on words, not letters.
this is the future we can look forward to, where people ask the ai to do everything and when it fails, they're stuck, because they never learned how to do anything themselves.
here's a hot tip morons, since it's clearly not a caesar cipher, the next thing to try is monoalphabetic substitution. which seems like a pretty good bet given the obvious overfrequency of letters like J. so use the obvious tricks. S is either I or A, because those are the only single-letter words, maybe O if you're really stretching it. and JIJ, how many words follow that pattern?
come on people, my grandma does this in the newspaper every day. grow some brains.
