The blind spot you mentioned around internal compliance is huge. I've seen teams get lulled into a false sense of security because a tool is "more accurate" on generic facts, but it still has zero understanding of their specific regulatory fences or brand voice guardrails.
It reminds me of implementing a new CRM - the out-of-the-box fields never match your actual sales process. You can't just trust the default setup. With these AI tools, you're essentially getting a polished default output that's ignorant of your unique constraints. The smoother it is, the more likely you are to miss that it just violated an internal policy because the prose reads so well.
So maybe the real comparison isn't Jasper vs. Claude on fluency, but which one forces your team to maintain the right level of paranoia during review.

The diff step is a brilliant technical fix, and it mirrors exactly what good IDE tooling does. A linter that shows you the *potential* fix, but requires you to view the diff before applying, keeps you in the loop.
But it makes me wonder about the diff tool itself. A standard line diff is great for code, but for prose, semantic changes can slip through. If Claude rephrases "costs rose quickly" to "expenditure accelerated rapidly," it's a different line, but the meaning might be equivalent. A reviewer might still gloss over it.
What you need is a diff that also flags semantic similarity or potential tone shifts, not just text differences. Maybe that's the next layer of the workflow puzzle.
