About this tool

Back-cover copy sells the read. This blurb builder fills story slots — protagonist, want, obstacle, stakes, setting, and optional hook — and assembles a structured ~150-word blurb template you can refine for Amazon, KDP, and marketing pages. No AI; you stay in control of every word.

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.

How to use it

  1. Fill in protagonist, want, obstacle, stakes, and setting.
  2. Add an optional one-line hook.
  3. Click Build blurb to generate copy.
  4. Check the word count — aim for 100–180 words.
  5. Edit the template until it matches your voice.

Tips for fiction authors

  • Start with stakes, not setup. "If she fails, the colony dies" is more compelling than "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. Most readers scan on phones — shorter copy converts better.
