Thankfully humans are great at pattern matching and it's trivial for me to "vet this ideation":
LLMs are notorious for getting subtleties wrong, and in legal agreements like terms of employment the subtleties are often of material import. Therefore this is a bad idea.
If you don't want to read/don't understand the terms of your job offer then pay a lawyer. Asking JobOfferGPT is just asking for trouble.
Reading yourself (at whatever level you are capable of and can tolerate) followed by asking an LLM to highlight any areas of the terms that are non-standard, may cause concern, could be restrictive, or might cost you later could help identify subtleties you might have missed.
Certainly it’d seem no worse and possibly better than just reading the terms, especially as a layperson.
