Format your description
Paste your blurb as you wrote it. Blank lines become paragraphs; a line wrapped in *asterisks* becomes bold; a line wrapped in _underscores_ becomes italic. Everything happens in this page — your text is never uploaded and never stored.
0 characters of HTML.
Then check the shelf it lands on
Formatting is the easy half. The half that moves copies is which Amazon shelf your words put you on — and that is the other free tool: the Blurb Shelf Check, which reads your blurb against the corpus below and tells you the shelf Amazon currently reads it onto.
Why this comes from real data
The reader-demand corpus behind the paid Ad Pack’s ad-copy scoring, Blurb Shelf Check and Reader Intel holds these counts (this tool runs in your browser and does not use it). They are live table counts, not marketing rounding — we count them ourselves and we publish the count.
Counted from live tables on 9 October 2026 (internal audit run IN-0823-2026-10-09). We never publish a customer's book, name or data — every figure above is a whole-corpus aggregate. Compared with template tools such as Canva, Placeit and BookBrush: you supply the cover and the words, and they lay them out. Our paid Ad Pack starts from your manuscript (or your book’s listing where none is supplied).
More free tools across the estate
Book Ad Pack is one of five sites run by Coral Hart Group on a shared reader-demand spine. These are the other free, no-signup tools and data views worth your time.
