AI Book Description Generator That Sounds Human — BookBlurb

AI Book Description Generator
Get 3 genre-tagged blurbs in seconds. Every variant ships with an AI-likeness score and a one-click human-voice polish — so you can post to Amazon without readers guessing your book was written by AI.
1 free credit per month · No card · Polish and export after free trial
Generate 1 free blurb per month — no card needed. Polish and export unlock with a free account.
Fill in the form and click Generate to see 3 description variants.
Every blurb ships with a deterministic 0–100 score and the specific phrases that triggered it. Not "model feels like AI" — six concrete signals scored objectively.
Hard-bans the flagged phrases, re-generates with your title, genre facts, and character names locked, then re-scores. Side-by-side, provable, not promised.
Toggle "AI-assisted" per export for platforms that require it. Amazon, Apple Books, Kobo, Barnes & Noble, iTunes — disclosure rules differ. Set your default in /settings.

You've finished the book. You love the story. You open Amazon KDP, paste in the description, and think: "Does this sound like me?"
You're not paranoid. r/selfpublish threads mock AI-sounding blurbs weekly. A 2025 Goodreads reviewer publicly accused a romantasy author of AI writing. Authors have been false-flagged by AI detectors for prose they spent years writing.
BookBlurb was built for the moment after the generation — not the moment of it. We can't tell you what to write. We can tell you when a phrase is going to get you accused.
