Write a polished book description in seconds with the free Book Description Generator. No sign-up, 56 languages, and adjustable tone & length.
A book's back-cover or Amazon description has to hook a browsing reader in a few short paragraphs — enough intrigue to sell the story without giving away the ending. The Book Description Generator writes compelling blurbs from your plot summary and genre.
Amazon and retailer-style back-cover blurbs that hit the classic beats: setup, stakes, and a hook — written to match your genre's conventions, whether that's thriller tension or romance chemistry.
Give it your protagonist, the central conflict, and what's at stake — not the whole plot. The best blurbs raise a question the reader has to buy the book to answer, so avoid resolving the tension in the description itself.
Self-published authors writing their own back-cover copy, indie publishers prepping a book launch, and writers who are great at fiction but find marketing copy a completely different skill.
Most retailer blurbs run 150-300 words — long enough to build intrigue, short enough that browsers actually read the whole thing.
No — a good blurb raises the central question and stakes without resolving them; save the ending for the actual book.
Yes — for non-fiction, describe the core problem your book solves and the description focuses on the reader's takeaway instead of plot tension.
