from my experience, it is really helpful when it comes to any sort of ideas, for example "I develop a game, I need some ideas on how to monetize it, how to build a community etc. ", it could help you with writing an essay, article, anything like those, but you need to know how to use it and be as much specific as you can. but when it comes to prompts like these : "tell me the main characters of a "enter any movie name" movie", "can you explain to me what is romanticism and who were the pioneers of this movement?", you know something that is needed to be verified, chatgpt can fuck it up and pretty much give you a total bullshit, that differs from the reality.
this thing is not perfect, but it totally could help you in some type of way, if you know when to and how to use it.
