> LLMs are useful for research and checking your work.

I have to disagree that it's good for LLMs to do the research, depending on the context.

If by "useful for research" you mean useful for tracking down sources that you, as the writer, digest and consider, then great.

If by "useful for research" you mean that it will fill in your citations for you, that's terrible. That sends a false signal to readers about the credibility of your work. It's critical that the author read and digest the things they are citing to.
