Pretty neat. This kind of tone self-moderation comes naturally to good communicators, but I know people (on and off the spectrum) who really, really need help with this, and it's cool to see LLMs are able to do this. There are a surprising number of people in the business world who are just totally unable to tone-police themselves. In the medical field I'd be worried about hallucinations, of course, but presumably your SIL fact-checks the output.
