I've found it very useful with organisational problems too. I had a complex issue to work through recently and tried working with ChatGPT, Claude and Grok 3 to optimise letters to some of the people involved to try to get things solved in the way I felt was fairest for all involved (anonymised, of course, with no memory on ChatGPT). One neat trick was to export the letter from one chat, then to start a fresh one, say that I am <role of recipient> and provide the letter and ask what it thinks -- basically red-teaming it.

The process of doing that clarified my thoughts and arguments so much that I never wound up having to send them -- I'd already made the right points on Slack and in meetings, and a compromise was achieved.
