Set filters and generate a back-cover draft
From blank page to a structured draft you can hand to an editor.
Match the commercial category of your book: romance, thriller, fantasy, and more, plus the emotional register you want on the back cover.
Create one or several blurb drafts in a batch. Read them aloud to hear rhythm and whether the hook fits your true opening.
Replace placeholders with your character names, setting, and stakes, then line-edit for clarity and comp titles for your market.
What you get in a back-cover and book description generator built for working authors.
Each draft is built as connected paragraphs: setup, pressure, and (for long form) a closing line that fits catalog copy.
Short, medium, and long modes so you can match Amazon, Ingram, or a physical jacket word count without starting from nothing.
Romance, mystery, thriller, fantasy, sci-fi, horror, literary, historical, contemporary, and YA—plus tone filters to stay on brand.
Run multiple seeds in one click when you are comparing “quiet” versus “gripping” marketing angles.
Send results straight to your doc, Vellum notes, or your editor in a single paste.
Your project details never leave the browser; generation is client-side only.

Compare how different tones position the same premise when feedback says the hook is unclear.
Keep back-cover language on voice while you vary the plot promise from book to book.
Draft short and long variants for jacket cards, digital bundle pages, and insert copy.
A simple framework to judge whether a generated book blurb is working—before you paste it into a store listing.
A strong blurb usually opens with a specific character want and a specific obstacle before the rest of the world rushes in.
Readers buy consequences: what is lost, what is learned, and what is still uncertain by the last line of the blurb.
Name the kind of book (romance, mystery, horror) through situation and language so the right audience self-selects.
Polish generated copy for Amazon, Ingram, and your own site without breaking reader trust.
If your title is a metaphor, the blurb is where a city, job, or relationship label can help discoverability when edited carefully.
A blurb that promises more spice or gore than the pages deliver can tank reviews; align tone with your content warnings.
Most readers first see your description in a narrow column; short paragraphs and strong verbs win the scroll.
