I like the idea as someone working in a regulated environment. We just paid ~$10k to a counsel to help craft our documents, but they are highly bespoke to our needs.

That being said, I don't know how much I'd trust the results without having a human legal review in the loop. Perhaps that could be an up-charge/add-on: partner with a few firm/counsel that has deep experience different niche regulated areas (e.g. FDA), and then say e.g. for an add'l $500, get a stamp of approval on the document from a counsel who is well-versed in the space.

It's perfectly reasonable for a process like this to be initiated by an expert, 80% created according to the input and initiation, with a full review at the end.

The expert could further imbue their expertise in what's created.

It goes without saying that basic generation attempts of text will only return the average of the corpus and not much more.
