tl;dr: Are there good services for editing-style AI feedback, which won't require me to copy-paste my work? Especially focusing on logical gaps, unclear sections, things-that-seem-missing, or ways I can be more concise.

longer: I write a lot of Amazon-style docs for my small business. Instead of getting feedback from my teammates and iterating, I'd like to do a first pass with AI feedback. I've been copy-pasting my docs whole into tools to get feedback, but this is clunky. Ideally I'd like something that could give me the feedback immediately or as I'm writing, like an AI editor. Perhaps it would be in-line, or in a side panel. I looked at some tools, but it seems many of the options are trying to write the doc for me. This just isn't what I need, I want the _insight_ that comes from writing a doc like this, not just the doc itself. Are there good services for editing-ish feedback?

I especially want feedback on logical gaps, unclear sections, things-that-seem-missing, or ways that I can be more concise. Grammar and spelling is much less important.
