What It Does
The Blurb Generator writes retail jacket copy - not a synopsis, not a query letter. It produces three complete variants (dramatic, voice-driven, punchy), each with a hook line, a spoiler-safe 100-180 word body, and a closing tagline, plus a short version for retail preview panes and a one-liner for social media.
It follows the rules that sell books: open on a hook, introduce protagonist and stakes fast, end on the open question - and it explicitly lists the twists it detected and deliberately avoided, so you never spoil your own book in marketing copy.
How to Use It
Select Project & Tone
Optionally set a tone ("dark and urgent", "witty") - otherwise it matches the book's own voice from your opening chapters.
Compare the Three Variants
Each takes a different marketing angle. Mix and match - a hook from one, a body from another. Copy any variant with one click.
Check the Do-Not-Reveal List
Use it as a spoiler firewall for ALL your marketing - ads, social posts, and retailer descriptions.
Estimated Credit Usage
Low-to-moderate cost - synthesis rather than deep manuscript analysis.
