Paste a blog — ideally one already run through Structure Map. Every paragraph gets tagged and linked to whatever it depends on, then you pick which ones to actually review. For each one you choose: verify it against a real source, restate it in your own words, and decide keep, correct, or flag. Anything you don't select passes through untouched.
This checks two different things, not one. Whether the paragraph's claim is factually supported by a real source — and separately, whether you personally understand and stand behind it. A paragraph can pass one check and fail the other. This app never calls an AI itself: it only writes the prompts you copy out and paste back in.
