About this tool
Back-cover copy sells the read, not the plot. Fill in the story slots — protagonist, want, obstacle, stakes, setting, and an optional hook line — and the builder assembles three short blurb drafts in different shapes, with a word count against the 100–180 words most Amazon descriptions run to. The drafts are a skeleton, usually 30–60 words: expand the one that fits your book in your own voice. No AI, and nothing leaves your browser.
What you can do
- Structured slots for protagonist, want, obstacle, stakes, and setting
- Optional one-line hook field for high-concept openings
- Word count display — aim for 100–180 words for Amazon
- Three draft shapes on each build to compare and combine
- No AI generation — you write the substance, the tool assembles structure
- Pairs with title length checker and AI Kindle description generator
- Private browser builder — blurb drafts never upload to servers
Write blurbs that sell the promise, not the plot dump
Store blurbs fail when they summarize the whole book. Use this builder to surface conflict, stakes, and genre tone in a short KDP-ready description you can refine before cover and keyword work.

- Edit the template until it matches your voice, then copy to KDP or your query.
Tips for fiction authors
- Start with stakes, not setup. "If she fails, the colony dies" beats "In a distant galaxy, a mechanic dreams of freedom."
- Name your protagonist in the blurb. Readers connect with named characters more than "a young woman" or "a detective."
- End your blurb with a question or dilemma, not a resolution. The reader should want to open the book to find out what happens.
- Keep blurbs under 180 words for Amazon mobile scanning. Most readers skim on phones — shorter copy converts better.
- Use this builder first for structure, then the AI Kindle description generator if you want Kestrel — Free to polish tone for your genre.

Common questions
Does this use AI to write my blurb?
No. It assembles your inputs into proven blurb structures. You edit every word. For AI-assisted copy, try the Kindle description generator.
How long should a fiction blurb be?
Amazon descriptions often work well at 100–180 words. The tool shows your word count as you build.
Can I get multiple versions?
Yes. Each build gives three versions of the same slots — a want-first line, a "never expected" line and a setting-first line — so you can pick the shape that fits and mix sentences between them.
Is this enough for KDP upload?
Not on its own. The drafts are a short skeleton; expand the one you like to 100–180 words in your own voice, then paste it into KDP's description field. For a full AI draft, use the book description generator.
Is my blurb uploaded?
No. The blurb builder runs entirely in your browser on Entangled Text.
