This thread is short and honestly not the most interesting thing in the world, but one point hit home:
It worked the best for things like sentence level help with wording, a final overall polish, and writing a conclusion.
What's worse than writing the conclusion of your five-paragraph essay? Nothing! Absolutely nothing! It's the most formulaic part of the whole production process, no wonder an LLM is good at it.
Honestly, it should be required to use ChatGPT to write the conclusion of a paper, and if it does a bad job it means you need to go back and make your previous paragraphs clearer.
