The Blurb reads your finished book and writes the words that sell it — an Amazon-ready description tuned to what your exact subgenre is demanding this month, not a fill-in-the-blanks template.
Run The Blurb →You get two blurb versions on different hooks to A/B, a structured data block for Amazon's Rufus AI, a subtitle plus seven keyword recommendations, category picks, and a plain-English market note with the live numbers behind it — so your listing is built on real demand.
The Blurb writes your blurb, subtitle and keywords from the finished manuscript. ShelfSmith fixes the placement of a book you're listing or have already listed — categories, BISAC, keywords and a blurb rewrite — from your blurb or your Amazon link, with no manuscript needed. Market Fit is the pre-writing market read, before you commit to the book.
Yes — The Blurb reads your finished manuscript so the description, keywords and market note reflect the book you're actually publishing.
No. It only uses tropes and elements your book actually contains, so the promise on the page is one your story keeps.
It's tuned to the romance market by subgenre, so the demand read, keywords and positioning are built for romance readers.
