The Blurb Section Is Where AI Detectors Bite

The blurb is the part of a query letter that gets screenshotted, shared on X/Twitter, and judged. BookBlurb scores that section exactly like the main tool — AI-likeness 0–100, flagged phrases inline, one-click polish that re-generates with the same hard-ban rules. Re-score is free if you edit the blurb yourself.
