The use case that I'm looking forward to try is to have it act as a peer-reviewer. It will get you the slightly generic misunderstanding, being not-quite-in-touch with the point you are actually trying to make, and it likes to get hung up on points that are not your main concern - well, just like it does with summaries. So you can adjust: emphasize, summarize, make implications more obvious etc. Once even ChatGPT gets what you are trying to say, there should be a much better chance that a reviewer will get it too.
