This 504 from Vercel is a result of ratelimit by OpenAI. I really can't do much since OpenAI has a stupid policy requiring API spending to reach 50$ before upping my rate-limit tier. Apologies. As for the wipeout, I will implement a localStorage to save your past attempts.
replyFor clarity, I wasn't commenting on fixing the 504s since that can be a lot of work but surely you have influence over what you're feeding into the JSON.parse in the client side that's wiping the input box?
