This is a structural editor that reviews your document before you even think about copy editing. It analyzes whether your content follows the right structure model (tutorial, reference, conceptual explanation, or something else), then proposes cuts, reorganizations, and simplifications while keeping your ideas intact. The interesting bit is the reader type toggle: set it to "humans" and it preserves things like examples and visual breathing room, set it to "llm" and it optimizes for precision over warmth. It won't rewrite your prose, just tell you what sections to move, merge, or delete. Works best when you give it purpose and audience context, though it will infer if you skip those inputs.
